The ground has staged two One Day Internationals: England against New Zealand in 1973, and a 1983 World Cup match between Pakistan and Sri Lanka.

In rugby league, Wales played thirteen matches at the ground between 1945 and 1978, two of which were part of the 1975 World Cup tournament.

However, before the move, the cricket infrastructure will be replaced with new stands for the rugby team, meaning Swansea CC will leave the stadium after around 150 years.

On 19 June 1928 the ground was the venue of a mile race, for Swansea Grammar School's Sports Day, won by a teenage Dylan Thomas; he carried a newspaper photograph of his victory with him until his death.

[6] Swansea Corporation discussed raising the capacity to 70,000 or even 82,000, but wartime bomb damage inflicted on the city forced a revision of building priorities.

Swansea RFC defeated New Zealand 11–3 at St Helen's on 28 September 1935, becoming the first club side to beat the All Blacks.

During the 1975 Rugby League World Cup, Australia defeated Wales 18–6 in front of 11,112 fans (this match was broadcast throughout the United Kingdom by the BBC).
