Statue of Oliver Cromwell, Westminster

The Parliamentary War Memorial, also known as the Recording Angel Memorial, is a stone sculpture in Westminster Hall, unveiled in 1922, which commemorates the members of both Houses of Parliament of the United Kingdom who died in the First World War. It names 22 members of the House of Commons, 20 members of the House of Lords, and 9 senior members of staff, together with another 94 sons of members and officers of the House of Commons, who lost their lives in the war. (Sons of peers and of officers of the House of Lords are commemorated on the wooden panels of the House of Lords War Memorial in the Royal Gallery.) Above the memorial is a large stained glass window which commemorates members and staff of both Houses who died in the Second World War.

Westminster Hall is a large medieval great hall which is part of the Palace of Westminster in London, England. It was erected in 1097 for William II ("William Rufus"), at which point it was the largest hall in Europe. The building has had various functions over the years, including being used for judicial purposes from the twelfth to the nineteenth centuries. When a joint address is given to the two chambers of the UK Parliament, the House of Commons and House of Lords, the hall is typically the venue. It was also used to host coronation banquets until the nineteenth century, and since the twentieth century has been the usual venue for the lyings in state of state and ceremonial funerals. The fabric of the hall is particularly notable for its hammerbeam roof, a form typical of English Gothic architecture which uses horizontal trusses to span large distances. The roof was commissioned for Richard II in 1393 and built by the royal carpenter, Hugh Herland. It is the largest clearspan medieval roof in England, measuring 20.7 by 73.2 metres (68 by 240 ft). At the same time the rest of the hall was remodelled by the master mason Henry Yevele. The renovations include eighty-three unique depictions of Richard's favourite heraldic badge, a resting chained white hart.

Old Palace Yard is a paved open space in the City of Westminster in Central London, England. It lies between the Palace of Westminster to its north and east and Westminster Abbey to its west. It is known as the site of executions, including those of Sir Walter Raleigh, Guy Fawkes and other conspirators of the Gunpowder Plot, and James Hamilton, 1st Duke of Hamilton, following the Battle of Preston. St Margaret Street/Abingdon Street divides Old Palace Yard into two parts, running diagonally from the north-west to the south-east. The eastern, larger part belongs to the grounds of the Palace of Westminster, the seat of the Parliament of the United Kingdom. To the north of the Yard is St Stephen's Entrance, the public entrance into the Palace, as well as the great South Window of Westminster Hall. Standing near this window and facing away from it is a bronze equestrian statue of Richard Coeur de Lion (King Richard I, also known as "Richard the Lionheart"). Created by Baron Carlo Marochetti, the statue was completed in 1856 and installed in its present location in 1860. The eastern side of Old Palace Yard is defined by the West Front of the Palace, which is part of the precincts of the House of Lords; the carriage porch of the Peers' Entrance marks the middle of this frontage, and the Victoria Tower its southern end. Access to this part of Old Palace Yard is restricted for security reasons by means of concrete barriers. For most of the year it is used as a car park for the House of Lords, but it is cleared of barriers and street furniture for the annual State Opening of Parliament, the formal opening of the legislative session by the British monarch. Conveyed from Buckingham Palace to Parliament in a horse-drawn carriage, the monarch passes through the Yard en route to the Sovereign's Entrance, at the foot of the Victoria Tower. The western part of Old Palace Yard is freely accessible to the public. To its west are located the Henry VII Chapel and the Chapter House of Westminster Abbey, while to its south stands 6–7 Old Palace Yard, the sole survivor of the row of houses that used to surround the Yard. The building is now part of the Parliamentary Estate. Close by is a statue of King George V, made of Portland stone; sculpted by Sir William Reid Dick and unveiled in 1947, it stands on a pedestal by Sir Giles Gilbert Scott and faces the Peers' Entrance of the Palace of Westminster. In 2002, an analemmatic sundial was fitted into the Yard's pavement in front of the statue, as a gift to Queen Elizabeth II from Parliament on the occasion of her Golden Jubilee.

Richard Coeur de Lion is a Grade II listed equestrian statue of the 12th-century English monarch Richard I, also known as Richard the Lionheart, who reigned from 1189 to 1199. It stands on a granite pedestal in Old Palace Yard outside the Palace of Westminster in London, facing south towards the entrance to the House of Lords. It was created by Baron Carlo Marochetti, an Italian sculptor whose works were popular with European royalty and the nobility, though often less well regarded by critics and the artistic establishment. The statue was first produced in clay and displayed at The Great Exhibition in 1851, where it was located outside the west entrance to the Crystal Palace. It was well received at the time and two years later Queen Victoria and Prince Albert headed a list of illustrious subscribers to a fund that aimed to raise money for the casting of the statue in bronze. Although the money was duly raised and the bronze cast of the statue was finally completed in 1856, a lengthy dispute delayed its installation for several years. The original idea had been to erect the statue as a memorial to the Great Exhibition. This prompted opposition, as did proposals to place it outside Charles Barry's newly completed Palace of Westminster. Various other locations to display the statue were initially considered before agreement was reached that it would be placed in Old Palace Yard, Marochetti's preferred location. It was installed in October 1860, though it was not until March 1867 that it was finally completed with the addition of bronze bas-reliefs on either side of the pedestal. The quality of the statue's workmanship caused problems during its first half-century; the horse's tail fell off the day after it was installed at the Great Exhibition, and forty years after its installation it was discovered to be riddled with holes and to have never been properly attached to its pedestal. It narrowly escaped destruction during the Second World War when a German bomb dropped during the Blitz landed a few metres away and peppered it with shrapnel. The pedestal and the horse's tail were damaged and Richard's sword was bent by the blast. In 2009, the Parliamentary authorities undertook a project to conserve and restore the statue.

St Stephen's Chapel, sometimes called the Royal Chapel of St Stephen, was a chapel in the old Palace of Westminster which served as the chamber of the House of Commons of England and that of Great Britain from 1547 to 1834. It was largely destroyed in the fire of 1834, but the Chapel of St Mary Undercroft in the crypt survived. The present-day St Stephen's Hall and its porch, which are within the new Palace of Westminster built in the 19th century, stand on exactly the same site and are today accessed through the St Stephen's Entrance, the public entrance of the House of Commons.

New Palace Yard is a yard (area of grounds) northwest of the Palace of Westminster in Westminster, London, England. It is part of the grounds not open to the public. However, it can be viewed from the two adjoining streets, as a result of Edward Middleton Barry, who also assisted with its landscaping, having used railings rather than walls or fencing in its design. The yard has existed since about the year 1100, but was greatly reduced in the 18th century to allow for the construction of new streets and buildings, the most notable of which is the wing taking up the eastern end and having the most prominent tower of the current palace. Speaker's Green fronts the Thames. An underground car park used by Members of Parliament is beneath. Before latest incarnations of the palace, the yard was an open public space used diversely such as for speeches, tournaments, pilloryings, and executions. It has twice been the scene of terrorist attacks.

The Imperial Monumental Halls and Tower was a proposed Gothic complex designed for a site in London adjacent to Westminster Abbey. The plans, exhibited at the Royal Academy in March 1904, included a 167-metre-high (548 ft) tower that would have dominated the Clock Tower and Victoria Tower of the nearby Houses of Parliament. It was never built. The design by John Pollard Seddon – then diocesan architect for London – and Edward Beckitt Lamb (son of Edward Buckton Lamb) was based on earlier schemes that each had proposed separately, and was one of many extensions proposed for Westminster Abbey in the late 19th and early 20th centuries by architects such as George Gilbert Scott, George John Shaw Lefevre, James Fergusson, and Henry Travis. In particular, the clergy at the abbey were concerned that it was becoming crowded with monuments, and more space was needed. Some of the proposed designs were considered by a Royal Commission in 1891. The issue was given added impetus after the coronation of King Edward VII and Queen Alexandra in August 1902, by a desire for Westminster Abbey to become a fitting Imperial monument, to compete with the baroque St Paul's Cathedral where Queen Victoria had commemorated her Diamond Jubilee in 1897. The architects aspired to create a grand and expensive monument to "form a worthy centre to the metropolis of the Empire 'upon which the sun never sets'". The complex was planned to be joined to the Great Cloister of Westminster Abbey, leading to a 65-foot-wide (20 m) reception hall beneath the tower, with the main body of the building – the Great Monumental Hall – stretching 192 feet (59 m) along Great College Street and incorporating smaller side halls. The halls would have ended with a double transept at the south end, 157 feet (48 m) wide and 47 feet (14 m) deep. The soaring Memorial Tower included a high-level open ambulatory, surmounted by a corona topped by a lantern with bells. It was intended to hold monuments and imperial trophies in galleries on the lower floors, with archives on the upper floors. It would have been the tallest building in the United Kingdom, significantly higher than the 111 metres (364 ft) dome of St Paul's Cathedral. The complex would have had a similar floor area to Westminster Abbey, and would have overshadowed the Houses of Parliament close by. The scheme of work would have included the completion of the tower over the crossing at Westminster Abbey. The Builder magazine criticised the scheme as exhibiting a degree of megalomania.

The Chapel of St Mary Undercroft is a Church of England chapel located in the Palace of Westminster, London, England. It had been a crypt below St Stephen's Chapel and had fallen into disuse, being used at various times as a wine cellar, dining room for Speakers (who had holes bored into the wall to accommodate two kitchen chimneys) and (now unconfirmed by records) stables for Oliver Cromwell's horses.After a fire had destroyed St Stephen's Chapel in 1834, the undercroft returned to its former use as a place of worship. Although much stonework was damaged in the fire, it was decorated in the 1860s by Edward Middleton Barry with gilded, painted and stenciled designs in rich colours to cover the walls, floor and vaulting. The backdrop of the altar depicts royal British saints. On the census night of 2 April 1911, suffragette Emily Davison hid in a cupboard overnight in the Chapel in order to be entered on the census form for the building as a way of ensuring her address was recorded as the House of Commons. A commemorative plaque, unveiled by Tony Benn in 1999, is fixed to the cupboard.It is still used for worship today. In particular, children of peers, who possess the title of "The Honourable", have the privilege of being able to use it as a wedding venue. In addition, members of Parliament and peers have the right to use the chapel as a place of christening in the baptistery and font (whose basin was made from a single slab of alabaster) designed by Barry.It is a Royal Peculiar chapel – outside the responsibility of any diocesan bishop. The building is administered through the Lord Great Chamberlain and Black Rod and it has no dedicated clergy: by convention services were conducted by the Rector of St Margaret's, Westminster, a member of the Chapter of Westminster Abbey. In 2010 the Speaker of the House of Commons used his right of appointment to nominate an outsider, Rev'd Rose Hudson-Wilkin, as the Speaker's Chaplain. The body of former Prime Minister Margaret Thatcher was kept in St Mary Undercroft on the night before her funeral in April 2013. The honour was also accorded for the body of Tony Benn, the long-serving Labour politician, before his funeral in March 2014, as well as that of PC Keith Palmer who was fatally stabbed carrying out his duties on the palace grounds during the 2017 Westminster attack.

The Parliament Square Peace Campaign was a peace camp outside the Palace of Westminster in Parliament Square, London, from 2001 to 2013. Activist Brian Haw launched the campaign at the site on 2 June 2001, initially as an around-the-clock protest in response to the United Nations economic sanctions imposed on Iraq. His protest grew broader following the war in Afghanistan and 2003 invasion of Iraq. He was joined by Barbara Tucker in December 2005, and stayed at the site day and night for nearly a decade. Tucker carried on the campaign following Haw's death in June 2011. The London Evening Standard reported in January 2013 that Tucker had started a hunger strike after protesting in the square for a total of eight years. The permanent protest camp was removed later in 2013.

The Henry VII Lady Chapel, now more often known just as the Henry VII Chapel, is a large Lady chapel at the far eastern end of Westminster Abbey, paid for by the will of King Henry VII. It is separated from the rest of the abbey by brass gates and a flight of stairs.The structure of the chapel is a three-aisled nave composed of four bays. The apse of the chapel contains the altar, and behind that, the tombs of Henry VII and his wife as well as of James I. There are five apsidal chapels.The chapel is noted for its pendant fan vault ceiling. The chapel is built in a very late Perpendicular Gothic style, the magnificence of which caused John Leland to call it the orbis miraculum (the wonder of the world). The tombs of several monarchs including Henry VII, Edward VI, Mary I, Elizabeth I, James I, Charles II and Mary, Queen of Scots are found in the chapel.The chapel has also been the mother church of the Order of the Bath since 1725, and the banners of members hang above the stalls.

The statue of George V in Old Palace Yard, Westminster, London, is a sculpture of George V, King of the United Kingdom and the British Dominions, and Emperor of India. The statue was sculpted prior to the Second World War and was hidden in a quarry during the war years. Other locations were suggested for the statue, including Parliament Square, but it was unveiled opposite the House of Lords in 1947.

A statue of Margaret Thatcher, the first female prime minister of the United Kingdom, stands in the Members' Lobby of the Houses of Parliament in London. It is a bronze sculpture of Margaret Thatcher, the first female Prime Minister of the United Kingdom. It was commissioned in 2003 following a change in rules to allow the depiction of living prime ministers in Parliament under certain conditions. The bronze statue, sculpted by Antony Dufort, was unveiled on 21 February 2007 by Michael Martin, Speaker of the House of Commons, with Thatcher in attendance.
