Many of the historic buildings in the Portsmouth area are at risk of being lost forever.
Historic England has published 2026’s Heritage At Risk register, highlighting the landmarks which need immediate attention and preserving. Two structures have been added to this year’s list, with none being taken off.
The register covers all listed buildings, scheduled monuments, conservation areas, registered parks and gardens and other categories. Claudia Kenyatta CBE and Emma Squire CBE, Co-CEOs of Historic England, said: “Our historic buildings and places help tell the story of where we live and contribute to the character and identity of local communities.
“Each year, the Heritage at Risk Register showcases the positive impact that restoring and reusing these special places can have. The most effective way to protect our buildings is to bring them back into use as places that create connection and enjoyment for local people.
“The sites saved and removed from the Register this year show what can be achieved when partners and communities work together to deliver positive, lasting change. By working together, we can protect our heritage for generations to come.”
Heritage Minister Baroness Twycross added: "Every part of the UK is bursting with history, so it is vital we protect the heritage sites at the heart of communities which help tell the stories of our nation. That’s why our £1.5bn Arts Everywhere Fund is so important, supporting efforts to save more than 1,000 arts venues, museums, libraries, and heritage buildings across England.
“The Heritage at Risk Register plays a crucial role in identifying these historic places that need our support. This year’s Register is an important reminder of the pressures facing our historic environment, from ageing buildings and structural deterioration to the impacts of extreme weather. I want us to build on our progress to ensure our heritage is protected for generations to come.”
Here are 28 structures on the list. One of them not included in the gallery is the archaeological site of the Motte and bailey castle near Apple Dumpling Bridge, south of Rowner in Gosport.

21. Haslar Gunboat Yard - Gosport - Grade I listed building
A row of ten gunboat sheds and three maintenance workshops, designed in 1856 by William Scamp of the Admiralty Works Department as part of the Haslar Gunboat Yard for the housing and repair of British gunboats, and their successor craft, of the Royal Navy. The adjacent traverser system was used for their launch and movement. The site ceased to be used in the mid-1970s but remained in MOD ownership. Once vacant, its condition deteriorated, with only minimum maintenance undertaken. Historic England grant aided a feasibility study in 2019 to help find an appropriate new use for the site. It has been given a priority C grade and is in "very bad" condition. | Historic England
