Built Heritage maintains the Northern Ireland SMR Sites & Monuments Record for the six counties of Northern Ireland, holding information on approx. 15,000 sites. These range from Mesolithic camp sites, Bronze age landscapes
preserved under bog, through the Early Christian monasteries,
the castles of the Norman conquest and the defended houses
of the Plantation settlers.
Each site is stored individually on the NISMR database, with a unique reference number which ties together all the information
on the site. This information includes geographical details, such
as grid references and which townland & parish the site is in as
well as typological details - what the site is, what time period it
belongs to, any known site names etc. and there is a brief
description of each site, taken from historical sources and field
visits. There is also a list of available references for each site.
All the sites listed in the NISMR database can be located geographically using the Map Viewer
More detailed information, including details of sites, plans and
photographs, is also available from the Monuments and Buildings
held in Waterman House, Belfast.
