Athletics at the 2012 Summer Olympics

The London Stadium (formerly and also known as the Olympic Stadium and the Stadium at Queen Elizabeth Olympic Park) is a multi-purpose outdoor stadium at Queen Elizabeth Olympic Park in the Stratford district of London. It is located in the Lower Lea Valley, 6 miles (10 km) east of central London. The stadium was constructed specifically for the 2012 Summer Olympics and 2012 Summer Paralympics, serving as the track-and-field venue and as the site of their opening and closing ceremonies. Following the Games, it was renovated for multi-purpose use, and it now serves primarily as the home of Premier League club West Ham United. Land preparation for the stadium began in mid-2007, with the construction officially starting on 22 May 2008. The stadium held its first public event in March 2012, serving as the finish line for a celebrity run organised by the National Lottery. Holding 80,000 for the Olympics and the Paralympics, it re-opened in July 2016 with 66,000 seats, but with capacity for football limited to 60,000 under the terms of the lease. The decision to make West Ham United the main tenants was controversial, with the initial tenancy process having to be rerun. The stadium hosted the 2017 IAAF World Championships and 2017 World Para Athletics Championships (the first time both events were held in the same location in the same year). It hosts a round of the IAAF Diamond League each year, known as the London Grand Prix, sometimes called the London Anniversary Games. It also hosted several 2015 Rugby World Cup matches. The stadium can also hold concerts with up to 80,000 spectators and, due to its oval shape and relocatable seating, was deemed to have the potential to host other sports such as baseball and cricket. In June 2019, it hosted the first regular-season U.S. Major League Baseball game in Europe in which historic rivals the Boston Red Sox and the New York Yankees played a two-game series.

The 2012 Summer Paralympics opening ceremony was held on 29 August 2012, starting at 20:30 BST and marking the official opening of the 2012 Summer Paralympics in London, England. The show – named Enlightenment – had Jenny Sealey and Bradley Hemmings as its artistic directors, leading a team that included Jon Bausor as set designer and Moritz Junge as costume designer. Queen Elizabeth II officially opened the Games. The ceremony was performed in the Olympic stadium in London in front of a capacity audience of 80,000 people.

The opening ceremony of the 2012 Summer Olympics took place on the evening of Friday 27 July 2012 in the Olympic Stadium, London, during which the Games were formally opened by Queen Elizabeth II. As mandated by the Olympic Charter, the proceedings combined the ceremonial opening of this international sporting event (including welcoming speeches, hoisting of the flags and the parade of athletes) with an artistic spectacle to showcase the host nation's culture. The spectacle was entitled Isles of Wonder and directed by Academy Award-winning British film director Danny Boyle. Prior to London 2012 there had been considerable apprehension about Britain's ability to stage an opening ceremony that could reach the standard set at the Beijing Summer Games of 2008. The 2008 ceremony had been noted for its scale, extravagance and expense, hailed as the "greatest ever", and had cost £65m. In contrast, London spent an estimated £27m (out of £80m budgeted for its four ceremonies), which was nevertheless about twice the original budget. Nonetheless, the London opening ceremony was immediately seen as a tremendous success, widely praised as a "masterpiece" and "a love letter to Britain".The ceremony began at 21:00 BST and lasted almost four hours. It was watched by an estimated worldwide television audience of 900 million, becoming the most-viewed Olympic opening ceremony in both the UK and US. The content had largely been kept secret before the performance, despite involving thousands of volunteers and two public rehearsals. The principal sections of the artistic display represented Britain's Industrial Revolution, National Health Service, literary heritage, popular music and culture, and were noted for their vibrant storytelling and use of music. Two shorter sections drew particular comment, involving a filmed cameo appearance of the Queen with James Bond as her escort, and a live performance by the London Symphony Orchestra joined by comedian Rowan Atkinson. These were widely ascribed to Britain's sense of humour. The ceremony featured children and young people in most of its segments, reflecting the 'inspire a generation' aspiration of London's original bid for the Games.The BBC released footage of the entire opening ceremony on 29 October 2012, edited by Danny Boyle and with background extras, along with more than seven hours of sporting highlights and the complete closing ceremony.

The closing ceremony of the 2012 Summer Paralympics, also known as The Festival of the Flame, was held on 9 September at the Olympic Stadium in London. Kim Gavin (who also directed the closing ceremony of the 2012 Summer Olympics) served as director for the ceremony, while Stephen Daldry served as its executive producer. The ceremony was themed around festivals and the four seasons, and was set to music performed live by the British rock group Coldplay, also joined by special guest performers such as the British Paraorchestra, Rihanna and Jay-Z. In a formal handover ceremony, the Paralympic flag was passed from Boris Johnson, Mayor of London, to Eduardo Paes, Mayor of Rio de Janeiro, the host city of the 2016 Summer Paralympics. During his closing speech, International Paralympic Committee president Philip Craven congratulated London for hosting "the greatest Paralympic Games ever." Following the official closure of the Games, the Paralympic cauldron was extinguished by swimmer Eleanor Simmonds and sprinter Jonnie Peacock.

The closing ceremony of the London 2012 Summer Olympics, also known as A Symphony of British Music, was held on 12 August 2012 in the Olympic Stadium, London. The chief guest was Prince Harry representing Queen Elizabeth II. The closing ceremony was created by Kim Gavin, Es Devlin, Stephen Daldry, David Arnold and Mark Fisher. The worldwide broadcast began at 21:00 BST (UTC+1) and finished on 13 August 2012 at 00:11, lasting three hours and eleven minutes. The stadium had been turned into a giant representation of the Union Flag, designed by Damien Hirst. Around 4,100 people partook in the ceremony; which reportedly cost £20 million. The 2012 Summer Olympics were officially closed by Jacques Rogge, who called London's games "happy and glorious." The ceremony included a handover to the next host city for the 2016 Summer Olympics, Rio de Janeiro and saw the Olympic flame extinguished and the Olympic flag lowered. The main part of the evening featured a one-hour symphony of British Music as a number of British Pop acts appeared. Tributes to John Lennon and Freddie Mercury and the fashion industry were included in the section. Rio marked the handover with an eight-minute section known as "Embrace" created by Cao Hamburger and Daniela Thomas, featuring Pelé. Sebastian Coe gave a speech, and the volunteers of London 2012 were thanked. An average of 23.2 million viewers in the United Kingdom watched the event, with an estimated 750 million worldwide. Critics were generally positive, but noted that it was not as good as the opening ceremony. Some of the foreign reviews questioned whether everyone would have understood the nods to British film and television. George Michael was roundly criticised for his song choice while Kate Moss, Naomi Campbell and Russell Brand were criticised for not demonstrating the Olympic ethos in their past behaviour. Some performers were initially reluctant to appear, and other high-profile acts turned down invitations to perform at the ceremony. NBC in the United States, TV5 in the Philippines and Prime TV in New Zealand were criticised by viewers for their broadcasts of the ceremony. There was also a concert in Hyde Park to close the Olympics, featuring Blur, New Order, and The Specials.

The Olympic Bell was commissioned and cast for the 2012 London Olympic Games, and is the largest harmonically-tuned bell in the world. Cast in bronze bell metal, it is 2 metres (6 ft 7 in) high with a diameter of 3.34 metres (10 ft 11 in), and weighs 22 long tons 18 cwt 3 qr 13 lb (51,393 lb or 23.311 t). The bell is now displayed in the Olympic Park.

The ArcelorMittal Orbit (often referred to as the Orbit Tower or its original name, Orbit) is a 114.5-metre (376-foot) sculpture and observation tower in the Queen Elizabeth Olympic Park in Stratford, London. It is Britain's largest piece of public art, and is intended to be a permanent lasting legacy of London's hosting of the 2012 Summer Olympic and Paralympic Games, assisting in the post-Olympics regeneration of the Stratford area. Sited between the Olympic Stadium (now called London Stadium) and the Aquatics Centre, it allows visitors to view the whole Olympic Park from two observation platforms. Orbit was designed by Turner-Prize winning artist Anish Kapoor and Cecil Balmond of Arup Group, an engineering firm. Announced on 31 March 2010, it was expected to be completed by December 2011. The project came about after Mayor of London Boris Johnson and Olympics Minister Tessa Jowell decided in 2008 that the Olympic Park needed "something extra". Designers were asked for ideas for an "Olympic tower" at least 100 metres (330 ft) high: Orbit was the unanimous choice from proposals considered by a nine-person advisory panel. Kapoor and Balmond believed that Orbit represented a radical advance in the architectural field of combining sculpture and structural engineering, and that it combined both stability and instability in a work that visitors can engage with and experience via an incorporated spiral walkway. It has been both praised and criticised for its bold design, and has especially received criticism as a vanity project of questionable lasting use or merit as a public art project. The project was expected to cost £19.1 million, with £16 million coming from Britain's then-richest man, the steel tycoon Lakshmi Mittal, Chairman of the ArcelorMittal steel company, and the balance of £3.1 million coming from the London Development Agency. The name "ArcelorMittal Orbit" combines the name of Mittal's company, as chief sponsor, with Orbit, the original working title for Kapoor and Balmond's design. The ArcelorMittal Orbit temporarily closed after the 2012 Olympic and Paralympic Games while the South Plaza (in which Orbit is positioned) underwent reconstruction for its long-term legacy use as a public outdoor space. It re-opened to the public on 5 April 2014. The structure incorporates the world's tallest and longest – 178 m (584 ft) – tunnel slide, designed by Carsten Höller. The idea was originally envisioned by the London Legacy Development Corporation as a way to attract more visitors to the tower. The slide includes transparent sections to give a "different perspective" of the twisting red tower and was completed in June 2016. This follows an option to abseil down the tower, introduced in 2014.

Bow Back Rivers or Stratford Back Rivers is a complex of waterways between Bow and Stratford in east London, England, which connect the River Lea to the River Thames. Starting in the twelfth century, works were carried out to drain Stratford Marshes and several of the waterways were constructed to power watermills. Bow Creek provided the final outfall to the Thames, and the other channels were called Abbey Creek, Channelsea River, City Mill River, Prescott Channel, Pudding Mill River, Saint Thomas Creek, Three Mills Back River, Three Mills Wall River and Waterworks River. The rivers have been subject to change over centuries, with Alfred the Great diverting the river in 896 to create a second channel, and Queen Matilda bridging both channels around 1110 by paying for the construction of Bow Bridge. Because the river system was tidal as far as Hackney Wick, several of the mills were tide mills, including those at Abbey Mills and those at Three Mills, one of which survives. Construction of the New River in the seventeenth century to supply drinking water to London, with subsequent extraction by waterworks companies, led to a lowering of water levels, and the river was gradually canalised to maintain navigation. Significant changes occurred with the creation of the Lee Navigation in 1767, which resulted in the construction of the Hackney Cut and the Limehouse Cut, allowing barges to bypass most of the back rivers. A major reconstruction of the rivers took place in the 1930s, authorised by the River Lee (Flood Relief) Act, but by the 1960s, commercial usage of the waterways had largely ceased. Deteriorating infrastructure led to the rivers dwindling to little more than tidal creeks, and they were categorised in 1968 as having no economic or long-term future. However, British Waterways decided that their full restoration was an important aim in 2002, and the construction of the main stadium for the 2012 Summer Olympics on an island formed by the rivers provided funding to construct a new lock and sluices which stabilised water levels throughout the Olympic site. It was hoped that significant amounts of materials for the construction of the Olympic facilities would be delivered by barge, but this did not happen. Improvements to the channels which form a central feature of the Olympic Park included the largest aquatic planting scheme ever carried out in Britain.

Carpenter's Road Lock is a rising radial lock in the London Borough of Newham, near Marshgate Lane in Stratford, England. It is located on the Bow Back Rivers and was constructed in 1933/34. It is the only lock in Britain with rising radial gates at both ends. British Waterways were hoping to restore it as part of the upgrade to Bow Back Rivers which took place for the 2012 Summer Olympics, but the gantries which enabled the gates to be raised were demolished to accommodate a wide bridge giving access to the main stadium. After the Games, most of the overbridge was removed. Funding for the restoration of the lock was in place by early 2016, and it is expected to be brought back into use in 2017.

Waterworks River is a river, at one time a tidal river, in the London Borough of Newham, one of the Bow Back Rivers that flow into the Bow Creek part of the River Lea, which in turn flows into the River Thames.The river is an artificial channel, cut for the Stratford Waterworks (later purchased by the East London Waterworks Company) in 1743, from the Old River Lee channel (above Old Ford Lock), to supply a reservoir at Saynes Mill, Stratford. It was widened to 100 feet (30.5 m) in the 1930s, as part of a project to prevent flooding in Stratford. The channel is lined for large stretches with concrete slabs, though sections through the Queen Elizabeth Olympic Park have been landscaped to a more natural setting. Whilst running through the park, which hosted the 2012 Summer Olympics, the river forms the border between the London Aquatics Centre on one bank, and the Olympic Stadium on the other. Steles (Waterworks) by artist Keith Wilson was the first artwork completed in the Olympic Park. It consists of thirty-five brightly coloured stele-like sculptures rising from the river.

The Old River Lea is the former natural channel of the River Lea below Lea Bridge, in the London Borough of Hackney. The Old River forms a large meander from the Middlesex Filter Beds Weir to rejoin the main channel of the River Lee Navigation below Old Ford Lock, just west of the 2012 Olympic stadium. The natural channel is joined by the River Lee Flood Relief Channel, and Dagenham Brook and a number of subsidiary channels to form the semi-tidal Bow Back Rivers, discharging into Bow Creek. The natural channel forms the boundary between the London Boroughs of Hackney and Waltham Forest; and forms the eastern boundary of Hackney Marshes, and historically the western boundary of Leyton Marshes.

The Big Breakfast is a British breakfast light entertainment television programme that was broadcast on Channel 4. Originally presented by Chris Evans and Gaby Roslin, the show was latterly presented by Mo Gilligan and AJ Odudu. The programme was distinctive for broadcasting live from a real house (which had been lock-keepers' cottages), commonly referred to as "The Big Breakfast House", or more simply, "The House", located on Fish Island, in Bow in east London. The original house on Fish Island in Bow has since been sold. The show was a mix of news, weather, interviews, audience phone-ins and general features, with a light tone which was in competition with the maturer GMTV and BBC Breakfast programmes.
