About the Castle
Calshot Castle was built by Henry VIII in 1539, as part of his chain of defences along the English south coast. At the time invasions were feared from the French and Spanish navies, and the Castle was built on a shingle spit close to the deep water channel at the mouth of Southampton Water.
Calshot Castle is owned by English Heritage and managed by Calshot Activities Centre. You can visit the castle throughout the summer months.
The Castle is surrounded by a deep moat. Please park carefully and keep children under close supervision at all times due to the steep drop and risk of drowning.
