Unlocking Essex’s Past and the Essex Historic Environment Record (EHER)

11 August 2011

Unlocking Essex’s Past (UEP) is a website that makes it possible for anyone to search the Essex Historic Environment Record (EHER) online, making information about the heritage of the county more accessible and encouraging exploration and conservation. The EHER is also accessible on the Heritage Gateway alongside information from other historic environment records in the East of England, and from English Heritage’s national records.

The EHER is a database of all known archaeological sites and monuments, historic buildings and parks and gardens in Essex. It is a comprehensive database of all items of historic interest within the current administrative county and Thurrock unitary authority. By collating information from a number of different sources, the EHER simplifies the research process and makes information more accessible.

The EHER contains over 30,000 records and the database is supported by an extensive library of photographs, national and local publications, and by an archive of other sources, including so called ‘grey literature’ (unpublished fieldwork reports), dissertations, and card indexes. The parts of the EHER are located by of a Primary Record Number (PRN).


The EHER is based in County Hall, Chelmsford, and can be consulted in person during normal office hours, Monday to Friday. To arrange a personal visit, please contact the Historic Environment Records team.
