Welcome to the online version of the Portsmouth Historic Environment Record (HER).

The HER database contains records of known archaeology, historic buildings, landscape features and other historic sites in Portsmouth from the prehistoric period to the present day. The HER is maintained by Portsmouth City Council's Museums Service and records are added and updated on a regular basis. Find out more about the HER. 

You can use the interactive map or text search to explore the records and discover more about the rich heritage of the city.

The online version of the HER is not a complete copy of the database and is not suitable for in-depth research or use in the planning process. Please see our terms and conditions.

If you have a commercial or academic enquiry you will need to contact the HER to request a full HER search. Please see the Portsmouth Historic Environment Record Access and Charging Policy for further information.
