These range in date from the mid-nineteenth century beginnings of photography to the present day . The vast majority of the Archive’s photographs are black and white, although some colour transparencies are held and colour photography is used to record distinctive historic colour schemes.
The Archive maintains an ongoing record photography programme, capturing buildings on film throughout the country, especially those in imminent danger of alteration or demolition. This record photography forms an important core to the photographic collections, and it is complemented by extensive holdings of historic images and important collections of photographs taken by individual architectural photographers and commercial photographic companies. The Archive also holds photographic copies of material in private and public collections in Ireland and abroad.
Within the confines of copyright legislation, copies of most of the photographs held by the Archive are available.
