The Wales national football team represents Wales in international association football. The team played their first match in March 1876 against Scotland before hosting their first home match the following year against the same opponent. The location selected for the fixture was the Racecourse Ground in Wrexham, the world's oldest international football ground still in use. The ground hosted all of Wales's matches until 1890, when a game was played against Ireland in the English border town of Shrewsbury. Wales played matches in several parts of the country, including Bangor, Cardiff, and Swansea over the following two decades.
The advent of professionalism in Welsh club sides saw the construction of several purpose-built football grounds. Two, Ninian Park in Cardiff, which hosted its first international in 1911, and Vetch Field in Swansea, which hosted its first in 1921, shared Wales's home matches with the Racecourse for nearly a century. Although one match was moved to Anfield in Liverpool in 1977 as a result of crowd trouble, no other venue would host a Wales home international fixture between 1910 and 1989 (when the team began playing at the National Stadium in Cardiff). Construction of the Millennium Stadium in Cardiff was completed in 2000, and it was immediately named as the side's new home ground. Although attendance was initially high at the Millennium, a gradual drop saw the team play matches in several newly built grounds (including the Cardiff City Stadium and the Liberty Stadium). The former was popular, and was credited as a factor in the team's improvement; it was subsequently designated Wales's permanent home venue.
Since the team's first match, sixteen grounds have hosted a Wales home international. The Racecourse has held more matches than any other venue with 94 by January 2020, 12 more than the second-most-frequently-used ground, Ninian Park, which was demolished in 2009. Four home matches have been held outside Wales; three were played at Anfield in Liverpool, and one at the Old Racecourse in Shrewsbury.
