Using York's Historic Environment Record

Our Historic Environment Record information policy

The aim of York's Historic Environment Record (HER) is to bring together information about the archaeology, historic buildings and historic landscapes of the City of York for everyone’s benefit.

Purpose of the York Historic Environment Record

The HER an important starting point for conservation, fieldwork and research into the historic environment and also informs local communities about their area. Using the information contained in the HER can help public understanding and enjoyment of the local historic environment. The HER originally developed as a planning control tool, to identify where historic remains are likely to be affected by development. Although this is still probably the most frequent use of the HER, its remit has expanded to include land-use planning and conservation initiatives, as well as research, tourism, education and local history projects. It is managed in accordance with national standards of good practice.

HER database content and links

The City of York Historic Environment Record (HER) includes a database (HBSMR by Exegesis Spacial Data Management) that holds information about remains from the prehistoric period to the present day, archaeological events (watching briefs, excavations, aerial photographs etc), and a collection of digital reports on these events. These provide information on nationally designated (conservation areas, listed buildings, registered parks and gardens and scheduled monuments), locally designated and undesignated heritage assets.

The database is linked to a series of digital maps held as Geographic Information System (GIS) files. The maps contain geographical depictions of all sites on the database, ranging from simple point locations to complex plots of extensive sites such as ancient field systems. Maps provided from the HER GIS are for information purposes only. Due to Ordnance Survey copyright restrictions this mapping must not be reproduced in researcher’s own reports.

Searches of the HER provide information selected from the record, normally for a defined area, although bespoke searches can also be done for particular periods or types of records. The data includes references to other sources held outside the HER.

The HER is constantly being enhanced, and the absence of a record should not be relied upon as indicating a lack of heritage interest, other national or specialist sources may contain information not held or indexed.

The HER tries to be responsive to the needs of existing users, to be proactive in identifying potential new users, and to seek out and overcome any barriers that may exist to using the record.

We maintain a log of all enquiries (following GDPR compliance). The resulting data is regularly reviewed to inform the development of the service.
