When the land surrounding Stade Toulousian's home ground, the Stade des Ponts Jumeaux, was expropriated by the local government in order to build a motorway, they were compelled by law to offer the club land and funding to build identical facilities in exchange for the expropriation.

[2] The Stade Ernest-Wallon was opened on 4 December 1983 with an international rugby union fixture; a first-division FIRA Trophy match which saw France's national team defeat Romania.

During the 1991 Rugby World Cup held in France, the stadium hosted a single game; a pool 4 match that saw Gabriel Vlad make his international debut for Romania in a defeat against Canada.

[14] In international rugby league competition, France's national men's team have played three matches at the Stade Ernest-Wallon; two friendlies – a loss to Australia in November 2004, and a loss to England in June 2008 – and a Four Nations match in October 2009 which France lost to New Zealand.
