The most recent ‘at risk’ register lists 25 local buildings from across the Portsmouth area including brickworks, military buildings and boatyard buildings and outlines the action needed to preserve these historical gems. The public body said the programme shines a light on historic sites most in need and has brought local people together in caring for and enjoying their heritage.
However huge strides have been made to protect some of these sites including at Fort Widley, where the Victorian military fort turned activities and equestrian centre, is making good progress to being saved following recent conservation work.
Fort Widley is a Victorian military fort built between 1861 and 1870 on top of Portsdown Hill, overlooking the city and is is part of a group of forts known as the Palmerston Forts, which were built to defend Portsmouth from a possible French invasion. These forts were never used in battle, and some people later called them “Palmerston’s Follies” because the threat never came.
During the World Wars, Fort Widley was used for storage, troop movement, and later as a bomb disposal and command centre, and then the 1960s, it was taken over by Portsmouth City Council. It is now managed by the Peter Ashley Activity Centres Trust under a full repairing lease from the council. The site is home to the Fort Widley Equestrian Centre and offers community room and space hire, as well as a hub for heritage tours.
It is listed as a Scheduled Monument and currently on the Heritage at Risk Register but is making good progress towards its removal. A grant of £270,957 from Historic England to conserve the six-foot bridges that lead into the former barrack block has greatly increased accessibility for the community.
Darren Bridgman, Chief Executive, Peter Ashley Activity Centres Trust said: "The conservation work at Fort Widley marks a really positive step in safeguarding one of Portsmouth’s most unique heritage landmarks. The repairs to the bridges have not only protected an important part of the fort’s historic fabric but also improved access for the community, opening up new opportunities for education, community use and inclusion.
“We are extremely grateful to Historic England and Portsmouth City Council for their support and proud to play a part in ensuring the fort continues to inspire future generations.”
Other sites where huge progress is being made is at Gilkicker Fort in Gosport which is in the process of being transformed into new homes (see the video embedded in this story), and at No 2 Battery in Gosport, home to The Diving Museum, which is undergoing a refurbishment.
Another success story is Bastion No. 1 in Gosport, a late 18th century bastion, which is now a public green space and has been saved thanks to the work of the local community and has been removed from the ‘at risk’ register.
Bastion No.1 is part of the old defences of Gosport. It was built between 1797 and 1802 as part of a larger line of earthworks and forts called the Gosport Lines, and is one of the last surviving examples of this kind of military defence in an English town.
These defences were designed to protect Portsmouth Harbour from attack. At one point, the bastion would have had cannons mounted on it, as well as a moat that would be flooded to make it hard for enemies to cross.
In the 1950s, Gosport Council bought the land and subsequently restored the site in the 1980s, so that locals could visit. Scheduled as a monument in the 1970s, it is now a public green space, and thanks to the work of Friends of Bastion No. 1 & Gosport Borough Council, funded by the Gosport Heritage Action Zone & Coastal Communities Fund, it has been saved and removed from Historic England’s Heritage at Risk Register.
Richard Whittington, Principal Conservation and Design Officer, at Gosport Borough Council said: "The removal of Bastion No.1 from the Heritage at Risk Register reflects the hard work and dedication of all those involved. This includes the Friends of Bastion No. 1, Gosport Borough Council and Historic England, who were funded by the Gosport Heritage Action Zone & Coastal Communities Fund.
“Its removal from the Heritage at Risk Register will help protect Bastion No.1's legacy, allowing the public to continue to enjoy this much-loved local landmark for years to come. The Heritage Action Zone project also produced a Conservation Management Plan for Bastion No.1 to ensure its future upkeep."
Historic England said around 6,800 historic sites have been rescued over the past 25 years – equivalent to around three-quarters of the entries on the original register from 1998 and that being on the ‘at risk’ register can help to attract much-needed funding or assistance to take action.
Claudia Kenyatta CBE and Emma Squire CBE, Co-CEOs of Historic England, said: “The heritage we see all around us impacts how we feel about our local places. The annual Heritage at Risk Register gives us the opportunity to celebrate the many benefits of bringing our historic buildings back into use.
“The best way to protect our buildings is to reuse them, turning them into places of local connection and joy. The sites that have been saved and have come off the Register this year really highlight the benefits of working together in partnership, and with communities, to create positive, sustainable change. Together we can safeguard our heritage for future generations.”

13. Church of St Cuthbert, Hayling Avenue, Portsmouth
Built in 1914-15 by E Stanley Hall, the original east end apse was destroyed by bombing, and the present east end wall is a post-war reconstruction. This has been remodelled to provide community facilities and the present church sits in the western two bays of the former nave of the church only. The roofs over the worship space and the bell tower are in poor condition. A National Lottery Heritage Fund Grants for Places of Worship scheme grant was used to develop the project, but funding for repairs has yet to be found. The Grade II listed building is described as being in a poor condition. Photo: Google Maps

14. Fort Cumberland, Fort Cumberland Road, Eastney
The coastal fort of 1746-1812 with later buildings and features is in need of some TLC with the casemates are suffering from water ingress and associated decay. In addition, there is localised deterioration of the Fort's defences, particularly the curtain and counterscarp, Historic England said. A programme of works to address some of the most urgent issues has been completed and the causes of water ingress into the casemates are being investigated. With local partners, Historic England is considering options for the sustainable re-use of the vacant parts of the site, both in the long and short-term. The site is home to a number of local businesses including the award-winning Portsmouth Distillery Company. The Scheduled Monument is described as being in poor condition.

15. Hilsea Lines - Centre Bastion (excluding casemates referred to as Bastion 4), East Centre Curtain (Railway) west side (formerly known as Bastion no. 5), Hilsea, Portsmouth
The Earthwork defence dating from 1858-1869 features batteries, magazines and barracks. The central section of the site, comprising three quarters of the Centre Bastion, and the west side of East Centre Curtain, where the railway enters Portsea Island (all formerly referred to broadly as Bastion no. 5) are continuing to suffer from heritage crime, a lack of regular maintenance and very limited access to the site. Opportunities to manage the monument, improve access, and reduce anti-social behaviour through the creation of a linear park using levelling up funding are being explored by Portsmouth City Council which last year held a consultation to help it draw up its plans. It has been given a priority B grade, meaning it has an "immediate risk of further rapid deterioration". The Scheduled Monument is described as being in a poor condition. | Louise Barnett

16. Horse Sand Fort, Solent
Horse Sand Fort is a circular 19th century Royal Commission sea fort lying in the Solent 3.6km south east of Southsea Castle which was one of a chain of four sea forts in the Solent recommended by the Royal Commission on the Defence of the United Kingdom in 1860 and designed to protect Portsmouth dockyard from seaborne attack. The Fort also was armed during both World Wars. The Fort provides a visual reminder of the strategic importance of the Solent in the late 19th to earlier 20th century. The Fort currently has no sustainable use aside from occasional visitor tours, Historic England has said, and it was sold at auction in 2021. The Scheduled Monument is described as being in a poor condition. Photo: -
