Historic buildings at Royal Navy's HMNB Portsmouth and around dockyard "at risk" of decaying - pictures

Several historic buildings at HMNB Portsmouth and around the dockyard are “at risk” of decaying if they are not preserved.

English Heritage highlighted a cluster of sites, many of which are listed buildings. The public body lists locations which are in need of immediate attention so they can be preserved for future generations.

Work has been carried out on several sites which have been listed. Expansion conservation efforts have been undertaken to progress with Fort Widley, one of the many Palmerston forts built between 1861 and 1870.

Bastion No.1 in Gosport was removed from the list after being transformed into a public green space. The site is part of the old defences of Gosport, built between 1797 and 1802 as part of a larger line of earthworks and forts called the Gosport Lines.

While there have been recent success stories, many other locations need urgent action to be saved. HMNB Portsmouth contains various sites dating back to the 1700s and 1800s. Here are the sites at the naval base and around the dockyard on English Heritage’s at risk register.
