The Gwynedd Historic Environment Record (formerly known as the Sites and Monuments Record) aims to provide comprehensive information regarding the known archaeological and historical sites, monuments, buildings, artefacts and landscapes of north west Wales. Covering the former county of Gwynedd (now Ynys Môn, Gwynedd and western Conwy, and including the Snowdonia National Park), it holds over 17000 records collected from a variety of sources over the last 30 years. It is constantly being updated.
The HER covers all aspects of human activity in the landscape from early prehistory to the twentieth century without prejudice. Details of well- and lesser-known sites can be found, in addition to records generated by archaeological projects undertaken in the area.
Information is held in the form of a computerised database supported by digital mapping (a GIS). This is supplemented by collections of maps and paper records (including details of listed buildings and scheduled ancient monuments), slides, photographs (film and digital; both aerial and ground), historic maps, and a reference library of relevant texts and journals.
