The National Inventory of Architectural Heritage is the State’s survey of buildings from 1700 to today, county by county; each record gives a rating, dates, a type and an appraisal. Being on it is not legal protection: that is each council’s Record of Protected Structures.

What this data can and can’t tell you
- The National Inventory. The State’s survey of post-1700 buildings, made county by county since 1990 (NIAH); a few records are older. It records; it does not protect.
- Ratings. International and National: of significance across Ireland or beyond. Regional: in its region. Local and record-only buildings get no page here.
- Archaeology. The Sites and Monuments Record (National Monuments Service) lists known archaeological sites; the national monuments to visit and the sites with an encyclopedia article get pages here.
- Protection. Both registers are surveys, not protection: a building is protected by its council’s Record of Protected Structures, and no national open list joins the 31 councils’ records.
- The grade. Ireland’s History grade is not built yet: the page describes, and gives no grade.
