Welcome to the Irish Architectural Archive


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, and make it available to the public.

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.

The Archive is located at 45 Merrion Square.

The Irish Architectural Archive Architecture Gallery and first floor rooms are open from 10 am to 5 pm, Monday to Friday. Access is free.

Protocols for accessing the Irish Architectural Archive Reading Room have now returned to those that applied pre-Covid. For more see Access.

The Irish Architectural Archive is supported by the Arts Council.





The Irish Architectural Archive is in receipt of Shared Island funding to provide enhanced digitisation and accessibility for the all-island architectural records.



Material held by the Irish Architectural Archive may be consulted in the Archive’s Reading Room at 45 Merrion Square, Dublin 2.
