Historic Environment Record (HER)

We maintain the North Somerset Historic Environment Record (HER) which is a record of known sites, monuments, buildings, findspots and landscapes of historic value.  With over 8000 records, it’s a good starting point for anyone interested in researching North Somerset’s historic environment.

Our HER is now available to view online, on an interactive map base.

We get information for the HER database from a wide range of sources including oblique and vertical aerial photographs from 1946 to the present day, approximately 400 archaeological excavation and survey reports from 1990-2004 and old maps.

Our HER is also linked to a computerised mapping system which holds information about a site or find as well as a historic landscape characterisation for the former County of Avon and scheduled ancient monuments. The records hold information such as:

  • location
  • description
  • date
  • type
  • source

We assess planning applications against the HER to find their likely impact on the historic environment as part of the planning process, but the database can be used by anyone.  It’s a useful research tool for students, local history and archaeology societies, members of the public and other researchers.

For more information or to consult the HER contact our Archaeological Services team.  If you want to view the HER, you should give us as much information as possible such as a map showing the area you are interested in, or an OS grid reference number.  If you are giving us a grid reference number, you should also tell us how wide you need the search to be, we usually perform 500m or 1km radius searches.
