The new gym was financed by a Capital Grant from the Department of Sports, Art and Tourism, a loan from the IRFU and Connacht Branch funds.
The levy of 5 euro on entrance to Connacht games will also be used to furnish the loan repayments.
The equipment is of the highest quality and was generously sponsored by Elverys/Rugbytech.
Speaking at the opening were Mayor of Galway Padraig Conneely, President of the Connacht Branch Mick Grealish, IRFU President John Lyons, who performed the official opening, Frank Fahy TD and Connacht Rugby CEO Gerry Kelly.
The gym will also be used by Irish squads and will be available for use by clubs in the region inclusive of all sports.
