The Millennium Stadium (), known since 2016 as the Principality Stadium () for sponsorship reasons, is the national stadium of Wales in Cardiff. It has a retractable roof and a usual capacity of 73,931. It is the home of the Wales national rugby union team. Initially built to host the 1999 Rugby World Cup and replacing the National Stadium on the site known as Cardiff Arms Park, it has hosted other events including the Tsunami Relief Cardiff concert, the Super Special Stage of Wales Rally Great Britain, the Speedway Grand Prix of Great Britain and various concerts. It also hosted FA Cup, League Cup and Football League play-off finals while Wembley Stadium was being redeveloped between 2001 and 2006, as well as football matches during the 2012 Summer Olympics.
The stadium is owned by Millennium Stadium plc, a subsidiary company of the Welsh Rugby Union (WRU). The architects were Bligh Lobb Sports Architecture. The structural engineers were WS Atkins and the building contractor was Laing. The total construction cost of the stadium was £121million, of which the Millennium Commission funded £46 million.
The Millennium Stadium opened in June 1999 and its first major event was an international rugby union match on 26 June 1999, when Wales beat South Africa by 29–19 before a crowd of 29,000. With a total seating capacity of 73,931, it is the largest stadium in Wales and the fourth largest in the United Kingdom by capacity. It is also the second-largest stadium in the world with a fully retractable roof and was the second stadium in Europe to have this feature. Listed as a category four stadium by UEFA, the stadium was chosen as the venue for the 2017 UEFA Champions League Final, which took place on 3 June 2017 and was won by Real Madrid. In 2015, the Welsh Rugby Union announced a 10-year sponsorship deal with the Principality Building Society that saw the stadium renamed as the "Principality Stadium" from early 2016.
History Background
Until 1969, Cardiff RFC and Wales both played their home matches on the same pitch at Cardiff Arms Park, but all this changed in the 1969–70 season. As a result of an agreement between Cardiff Athletic Club and the WRU, the National Stadium project established that a new stadium for international matches and events was required, with Cardiff RFC moving to a new, purpose-built stadium on the original cricket ground at the site of the former Cardiff Arms Park stadium. By 7 April 1984 the National Stadium was officially opened. However, in 1994, a committee was set up to consider redeveloping the National Stadium, and by 1995 the WRU had been chosen to host the 1999 Rugby World Cup.
In 1995, the National Stadium, which was designed in 1962, only had a capacity of 53,000; other nations' stadia, such as Twickenham (England) with a capacity of 75,000, and Murrayfield Stadium (Scotland) with a capacity of 67,000, had overtaken it. France was also about to build the Stade de France, which would have a capacity of more than 80,000 for the 1998 FIFA World Cup. The original capacity of the National Stadium was 65,000, but this had been reduced to 53,000, due to the Taylor Report. 11,000 of 53,000 capacity was on the East Terrace and the conversion to an all-seater stadium would have reduced the stadium capacity still further to just 47,500.
In addition to the problems of capacity, the National Stadium was also very well hidden by the neighbouring buildings to the south in Park Street, Wood Street and to the east in Westgate Street, and also by Cardiff Rugby Ground in the north. It was only fully visible from across the River Taff in the west. Access to the ground was also very restricted with the main entrance being a narrow opening in Westgate Street to the east which was shared by both vehicles and spectators alike.
The options for the new stadium included adding a third tier to the existing National Stadium, or moving to a new site in Bridgend. This last option was projected to have 100,000 seats and was backed by Bridgend County Borough Council, the leader of which told The Times that idea of building a new national stadium stadium in Cardiff was "half-baked". However, the Bridgend plan was discounted because it would have required a vast car parking facility, and that would have put severe short-term pressures on the local transport infrastructure, creating traffic jams and pollution. The committee eventually chose a new stadium on the same site but with considerable increase in its capacity. It would also involve moving the alignment of the stadium from west–east to north–south. This was the option supported by the Millennium Commission. It would become the fourth redevelopment of the Cardiff Arms Park site. It was also decided that the new stadium should have a sliding roof to accommodate a multi-use venue, with a grass pitch for rugby and football. The only other sliding roofs in Europe at the time were at two Dutch stadia – the Amsterdam Arena, completed in 1996 with a capacity of 50,000; and Gelredome in Arnhem, a 30,000-capacity ground built from 1996 to 1998.
To remain on the Arms Park site, additional space had to be found to allow safe access and to provide room for the increased capacity and improved facilities. This was achieved by the purchase of adjacent buildings to the south and east and by the construction of a new £6 million River Walk by the River Taff on the western side of the stadium.
By 1999, the Millennium Stadium had replaced the National Stadium, Cardiff Arms Park, as the national stadium of Wales for rugby union and association football international matches. Cardiff RFC continued as before to play at Cardiff Arms Park rugby ground, which had replaced the cricket ground in 1969.
Construction
The stadium was designed by a team led by Rod Sheard at Lobb Sport Architecture, who later merged with HOK Sport to become Populous. The building contractor was Laing and the structural engineers were WS Atkins. Mike Otlet of WS Atkins designed the stadium's retractable roof, which was constructed by Kelsey Roofing Industries. Cimolai S.p.A. from Italy fabricated and erected the 72 steel plane frames for the stands and all the 4,500 components of the roof.
Construction involved the demolition of a number of buildings, primarily the existing National Stadium (Cardiff Arms Park), Wales Empire Pool (swimming pool) in Wood Street, Cardiff Empire Telephone Exchange building (owned by BT) in Park Street, the newly built Territorial Auxiliary & Volunteer Reserve building in Park Street, and the Social Security offices in Westgate Street.
The stadium was built by Laing in 1999 on the site of the National Stadium, with the head of construction being Steve Ager. It was built for the 1999 Rugby World Cup, for which Wales was the main host, with seven of the 41 matches, including the final, being played at the stadium.
The total construction cost of the stadium was £121 million, which was funded by private investment and £46 million of public funds from the Millennium Commission, the sale of debentures to supporters (which offered guaranteed tickets in exchange for an interest-free loan) and loans. The development left the WRU heavily in debt.
The Millennium Stadium was named as such in recognition of the Millennium Commission's contribution to the building.
The stadium was first used for a major event on 26 June 1999, when Wales played South Africa in a rugby union test match before a crowd of 29,000. Wales won 29–19: the first time they had ever beaten the Springboks.
2016 renaming
On 8 September 2015 it was announced that the Millennium Stadium would be renamed Principality Stadium as the result of a 10-year naming rights deal with the Principality Building Society. Some fans expressed opposition on social media.
On 22 January 2016, the Millennium Stadium was officially renamed as the Principality Stadium. The new name, written bilingually ("Stadiwm Principality Stadium") and covering of the upper stadium, was lit up at a special evening ceremony, to be followed by a festival to encourage grassroots rugby. The change of name also meant a change of logo for the Millennium Stadium. There were three designs shortlisted, and a panel, which included the former Wales international captain Ryan Jones and staff and members of the WRU and Principality Building Society, chose the final design. A spokesperson for the WRU said: "The new stadium logo takes its inspiration from the venue's iconic architecture; four spires, curved frontage and fully retractable roof."
Features
The all-seater stadium has the capacity for 74,500 supporters and features a retractable roof, only the second stadium of its type in Europe. When opened the stadium was the largest stadium with this feature in the world until the opening of the Cowboys Stadium in Arlington, Texas in the United States in 2009. It remained the largest in Europe until the renovations of the Bernabéu in Madrid, Spain were completed in 2024.
Additional seating is sometimes added for special events such as a rugby Test against the New Zealand All Blacks, or for the FA Cup Final. The current record attendance is set at just over 78,000, recorded at the Anthony Joshua v Carlos Takam fight, on 28 October 2017, in which Joshua successfully retained his WBA, IBF and IBO titles.
The natural grass turf was made up of a modular system installed by GreenTech ITM. It features built in irrigation and drainage. The pitch itself was laid on top of some 7,412 pallets that could be moved so the stadium could be used for concerts, exhibitions and other events.
In May 2014, after much trouble with disease and stability, the surface was removed and replaced with a more resilient interwoven sand based Desso pitch.
The four ends of the ground are called the North Stand, the West Stand, the South Stand and the East Stand. The South Stand was previously known as the Hyder Stand, until Hyder was sold while the East stand was called the BT Stand until the stadium was renamed in 2016. The stadium has three tiers of seating with the exception of the North Stand, which has two tiers. The lower tier holds 23,154 spectators, the middle tier holding 15,626 and the upper tier holding 35,151 spectators.
The stadium was slightly restricted in size due to its proximity to Cardiff Rugby Club's home in the adjacent smaller stadium within Cardiff Arms Park. The WRU were unable to secure enough funding to include the North Stand in the new stadium and the Millennium Commission would not allow any of its funds to be used in any way for the construction of a new stadium for Cardiff RFC. The WRU held talks with Cardiff RFC to see if it would be possible for the club to either move or secure funding for the Cardiff Arms Park to be re-developed, but these were unsuccessful. The stadium thus had to be completed with a break in its bowl structure in the North Stand, known colloquially as Glanmor's Gap, after Glanmor Griffiths, then chairman of the WRU and now a former president.
The superstructure of the stadium is based around four masts. The stadium was built from 56,000 tonnes of concrete and steel, and has 124 hospitality suites and 7 hospitality lounges, 22 bars, 7 restaurants, 17 first aid points, 12 escalators and 7 lifts. The stadium has 7 gates for access to the site; Gate 1 is from the River Walk via Castle Street (to the north), Gates 2 and 3 are via Westgate Street (to the east), Gate 4 which was renamed Gatland's Gate () in honour of Warren Gatland in November 2019, is for team-coaches, celebrity limousines and other uses via Westgate Street, Gate 5 is via Park Street (to the south) and Gates 6 and 7 are via the Millennium Plaza (also to the south).
