Munster will play their European Cup semi-final against Castres in the French town of Beziers.
The venue for the April 27th fixture had been uncertain, with a European Rugby Cup (ERC) statement last week saying a site had not yet been found after lengthy discussions.
It had been anticipated that the game would be staged in Lyon but the city’s municipal stadium was made unavailable for the game.
The ERC confirmed that the second semi-final between reigning champions Leicester and Welsh side Llanelli would be played on April 28th at English First Division football club Nottingham Forest's City Ground.
