Who is NIAH?
The National Inventory of Architectural Heritage (NIAH) maintains a central database of the architectural heritage of the Republic of Ireland covering the period since 1700 in complement to the Archaeological Survey of Ireland, which focuses on archaeological sites of the pre-1700 period. As of 2022, there are over 50,000 records in the database, including buildings, monuments, street furniture and other structures. It does not cover Northern Ireland. Buildings recorded in the database are given a rating, either national or regional.
