The Irish Architectural Archive was established in 1976 to collect and preserve material of every kind relating to the architecture of the entire island of Ireland. As a cumulative body of material the holdings of the Archive represent the greatest single source of information on Ireland's buildings and those who designed them. Those holdings are made available to the public in the Archive’s public reading room or though its exhibitions and lecture programmes. The Archive is located at 45 Merrion Square and is open to the public from 10 am to 5 pm, Tuesdays to Fridays. Access is free.
