Gothic Past is an open-access resource for the study of Ireland’s medieval buildings.The site showcases images from three significant collections of image archives housed in the Department of History of Art and Architecture, Trinity College. They include the Stalley Collection and the Rae Collection of medieval Irish architecture and sculpture: photographic images that were created and collected from the 1930s to the present day. A third archive contains the O’Donovan collection of Irish Gothic moulding profiles. These image collections have been a key primary resource for investigations carried out as part of Reconstructions of the Gothic Past, a thematic research project carried out in the Department of History of Art and Architecture at Trinity College from 2008 -2011. The project research and the website have been made possible through the provision of an IRCHSS research grant.
