The GAA and the Archdiocese of Dublin are planning to sell off a site for up to 1200 apartments in Drumcondra.
Croke Park bosses had previously been set to buy Church lands near the Archbishop's Palace on the Northside.
Now they've struck a deal with the Archdiocese of Dublin to bundle up nineteen acres for sale, aiming to sell to property developers, according to the Irish Times.
The GAA is plans to keep neighbouring land for new sporting facilities and a hotel on neighbouring lands.
The Church looks set to capitalise on the booming price of development land in the capital as it faces the growing cost of caring for aging clergy.
The Irish Times reports the deal could be worth a hundred million euro -- but it's not clear how the proceeds will be split.
