The 2018 Cardiff National Eisteddfod was held in Cardiff Bay, Wales, from 3 to 11 August 2018. It was the seventh time the National Eisteddfod of Wales had been held in Cardiff. The 2018 event was billed as the Eisteddfod with "No fences" because it dispensed with the traditional enclosed 'Maes', or entrance fees to the event location. It made a £290,000 loss, but its popularity led to the suggestion of future Eisteddfods without fences.

The Welsh Industrial and Maritime Museum was located in Butetown, Cardiff, Wales, prior to the Cardiff Bay regeneration in the late 1990s. The museum formed part of the National Museums and Galleries of Wales, now known as Amgueddfa Cymru – National Museum Wales and the first stage opened in 1977, and it closed just 22 years later in 1998. Construction of the museum began in October 1974. Exhibits included cars, a bus and tram, a lighthouse, a figurehead from HMS Hamadryad, the Sea Alarm tugboat and a replica of Richard Trevithick's 1803 locomotive, Pen-y-Darren. A permanent exhibition described the history of the docks and coal mining in South Wales.Dr Geraint Jenkins was curator of the museum from 1978 until 1987.The museum closed on 1 June 1998 to make way for the new Mermaid Quay shopping development. Its exhibits were redistributed to other museums and the Sea Alarm was scrapped. A new location for a similar museum, in Swansea, was not chosen until two years after the closure. The National Waterfront Museum opened in Swansea in 2005.

The Pierhead Building (Welsh: Adeilad y Pierhead) is a Grade I listed building in Cardiff Bay, Wales. One of Cardiff's most familiar landmarks, it was built in 1897 as the headquarters for the Bute Dock Company. The Pierhead Building is part of the estate of the Senedd (Welsh Parliament; Welsh: Senedd Cymru), which also includes the Senedd building and Tŷ Hywel. The clock on the building is unofficially known as the "Baby Big Ben" or the "Big Ben of Wales".

Mermaid Quay (Welsh: Cei'r Fôr-forwyn) is a waterfront shopping and leisure district in the Cardiff Bay area of Cardiff, Wales. The 14,000 m2 (150,000 sq ft) development was opened in 1999, and includes restaurants, bars, cafes and shops.

Cardiff Bay (Welsh: Bae Caerdydd; historically Tiger Bay; colloquially "The Bay") is an area and freshwater lake in Cardiff, Wales. The site of a former tidal bay and estuary, it serves as the river mouth of the River Taff and Ely. The body of water was converted into a 500-acre (2.0 km2) lake as part of a UK Government redevelopment project, involving the damming of the rivers by the Cardiff Bay Barrage in 1999. The barrage impounds the rivers from the Severn Estuary, providing flood defence and the creation of a permanent non-tidal high water lake with limited access to the sea, serving as a core feature of the redevelopment of the area in the 1990s. Surrounding the lake is a 4.25 sq mi (11.0 square kilometres) area of redeveloped former derelict docklands which shares its name. The area is situated between Cardiff city centre and Penarth, in the communities of Butetown and Grangetown. Its waterfront is home to notable attractions, in particular regarding Welsh politics; with devolved institutions such as the Senedd building (housing the Senedd, the Welsh Parliament), Pierhead Building and Tŷ Hywel; and cultural attractions including the Wales Millennium Centre and Norwegian Church. The presence of devolved institutions in Cardiff Bay has led to its name's use as a metonym for devolved Welsh politics. According to Cardiff Council, the creation of Cardiff Bay is regarded as one of the most successful regeneration projects in the United Kingdom. The 'bay' was formerly tidal, with access to the sea limited to a couple of hours each side of high water but now provides 24-hour access through three locks.The Cardiff Bay Wetlands Reserve is situated along the northern edge of the lake, on the site of a former salt marsh.

All Souls Chapel was a large chapel which stood at Cardiff Docks, near the present Roald Dahl Plass.

Lynette Deborah White (5 July 1967 – 14 February 1988) was murdered on 14 February 1988 in Cardiff, Wales. South Wales Police issued a photofit image of a bloodstained, white male seen in the vicinity at the time of the murder but were unable to trace the man. In November 1988, the police charged five black and mixed-race men with White's murder, although none of the scientific evidence discovered at the crime scene could be linked to them. In November 1990, following what was then the longest murder trial in British history, three of the men were found guilty and sentenced to life imprisonment. In December 1992, the convictions were ruled unsafe and quashed by the Court of Appeal after it was decided that the police investigating the murder had acted improperly. The wrongful conviction of the three men has been called one of the most egregious miscarriages of justice in recent times. The police insisted that the men had been released purely on a legal technicality, that they would be seeking no other suspects, and resisted calls for the case to be reopened. In January 2002, new DNA technology enabled forensic scientists led by Angela Gallop to obtain a reliable crime scene DNA profile. The extracted profile led police to the real killer, Jeffrey Gafoor, who confessed to White's murder and was sentenced to life imprisonment. Gafoor received a shorter minimum tariff (the length of time before a prisoner may be considered for parole) than had been given to the wrongfully convicted men, due to the reduction for a guilty plea, highlighting a controversial feature of the sentencing guidelines. In 2004, the Independent Police Complaints Commission (IPCC) began a review of the conduct of the police during the original inquiry. Over the next 12 months around 30 people were arrested in connection with the investigation, 19 of whom were serving or retired police officers. In 2007, three of the prosecution witnesses who gave evidence at the original murder trial were convicted of perjury and sentenced to 18 months imprisonment. In 2011, eight former police officers were charged with conspiring to pervert the course of justice. Their subsequent trial was the largest police corruption trial in British criminal history. A further four police officers were due to be tried on the same charges in 2012. In November 2011, the trial collapsed when the defence claimed that copies of files which they said they should have seen had instead been destroyed. As a result, the judge ruled that the defendants could not receive a fair trial and they were acquitted. In January 2012, the missing documents were found, still in the original box in which they had been sent to South Wales Police by the IPCC.

Cardiff Bay Opera House was a proposed centre for the performing arts in Cardiff Bay, Cardiff, Wales, conceived in the 1990s as a crucial part of the Cardiff Bay redevelopment project. One aim of the scheme was to create a new home for the Welsh National Opera company, which was then based in the New Theatre in Cardiff. The Wales Millennium Centre was built in its place and it opened in 2004. The plan, supported by the Cardiff Bay Development Corporation, was to construct a permanent home for Welsh National Opera on a site near the Inner Harbour, Cardiff Bay. An international design competition was held and was eventually won by the Iraqi-born architect Zaha Hadid. The Hadid design was called the Crystal Necklace by some in the media. However, the project failed to win financial support from the Millennium Commission, the body which distributed funds from the UK National Lottery.

Tŷ Hywel (Hywel House or Hywel's House) is a building in Cardiff, Wales, used by the Senedd (Welsh Parliament; Welsh: Senedd Cymru; formerly the National Assembly for Wales). It is named after the medieval king Hywel Dda (Howell the Good), King of Deheubarth in South West Wales.

It houses Members of the Senedd and their staff, as well as staff of the Senedd Commission. The Welsh Government also operates from the building and occupies one whole floor and part of another.

On 25 June 2008 the Prince of Wales officially opened Siambr Hywel, the National Assembly's youth debating chamber and education centre, based on the former debating chamber in Tŷ Hywel.Tŷ Hywel is part of the Senedd estate in Cardiff Bay, along with the Senedd building and the Grade 1 listed Pierhead Building in Cardiff Bay.
