Leinster's traditional home over the years has been Donnybrook Stadium in Donnybrook, Dublin 4. Donnybrook consists of a single covered stand and three sides of open terracing. A move across Dublin 4 to the RDS Arena for Leinster was needed to accommodate growing crowds, as the 6,000 capacity stadium had become too small. For this reason, Leinster have signed a long-term lease with the Royal Dublin Society to play home games at the RDS Arena. Donnybrook has since, been improved as a venue with the reconstruction of the grandstand in 2008 and remains an important venue for rugby union in Dublin. Due to limited space, it is unlikely that Donnybrook will undergo further redevelopment. Leinster A play their British and Irish Cup games in the stadium and the senior team have continued to hold certain pre-season friendlies in the stadium as well as most Leinster schools cup matches being held at the venue.
