Historic Environment Record

The Historic Environment Record (HER) for north-west Wales aims to provide comprehensive information regarding the known archaeological and historical sites, monuments, buildings, artefacts and landscapes in the former County of Gwynedd.

It holds around 20,000 records collected from a variety of sources since the late 1970s, and covers all aspects of human activity in the landscape from early prehistory to the twentieth century. Details of well- and lesser-known sites can be found, in addition to records generated by archaeological projects undertaken in the area.

Visitors to the HER are requested to sign the Trust visitor book, located in the main office, when they arrive.

HER users may use their own camera to photograph certain collections within the HER, having signed a copy of our HER Camera User Form .

If you have any special requirements due to disability, it would help us improve the quality of your visit if you are able to let us know when you book an appointment. Disabled access to the building is via a ramp located at the front of the Gwynedd Archaeological Trust offices. Although the Historic Environment Record is located on the first floor, we have good facilities on the ground floor and can ensure full access to the computerised facilities in the main office and consultation of all documents and reports.

We are committed to continually improving the service we offer HER users. To get this right we need your feedback: we encourage all HER Users, whether they have accessed the HER remotely or in person, to complete a HER User Feedback Questionnaire. Thank you!
