Lumps Fort

Lumps Fort is a fortification in Southsea featuring thick stone walls, gun emplacements, and elevated structures built into the landscape. From its raised positions, visitors can see across the Solent toward the Isle of Wight, and the grounds include developed gardens and planted areas.

Built between 1859 and 1869, this fort was constructed as part of Portsmouth's mid-19th century defensive network. During the Second World War, it served as a preparation site for a significant Royal Marines operation against occupied territories across the Channel.

The gardens feature Japanese-style landscaping and multiple varieties of roses that visitors can discover while walking through the grounds. These plants give the place a softer character beyond its military function.

The fort is open year-round and situated directly beside Southsea's seafront promenade with parking available nearby. Visitors can freely walk the outer grounds and enjoy views from the walls without formal restrictions.

The fort served as a training location for a daring raid by British commandos using explosive-laden canoes to strike at occupied enemy ports. This secret preparation reveals an unexpected role in special operations that went far beyond typical coastal defense.
