Hurst Castle

Hurst Castle is a historic artillery fortress and English Heritage site located on a remote shingle spit in Hampshire, England. Built by Henry VIII in the 1540s, it defended the western entrance to the Solent for over 400 years.

Where it is
The castle sits at the seaward end of Hurst Spit, extending 1.5 to 2 miles from Milford-on-Sea in the New Forest National Park. Because of its isolated location, there is no vehicle access to the site.

What you can do there
Explore the Fort: Wander through the original Tudor keep, discover secret passages, and visit the massive 19th-century armoured wings.
Climb for Views: Scale the Tudor keep for panoramic views across the Needles Passage to the Isle of Wight.
See Massive Artillery: View surviving 38-ton Victorian guns and exhibitions detailing the castle’s role through World War II.
Visit the Garrison Theatre: Explore what is possibly the last surviving theatre built by a garrison during the Second World War.
Lighthouse Exhibition: Learn about the history of the lighthouses on the spit, including the functioning High Light built in 1867.

Who should go and when
Who: It is ideal for families with children who enjoy exploring open spaces and “nooks and crannies,” history buffs, and nature enthusiasts. It is also very dog-friendly.
When: The best time to visit is during the main season from April to October, when the ferry service from Keyhaven is operational. August is often cited as an ideal month for weather.
Note: The castle is currently undergoing major preservation work and is temporarily closed until March 28, 2026.

Why it is unique and different
Unusual Longevity: Unlike many Tudor castles, Hurst remained in active military use until 1956.
Royal Prison: It famously served as a prison for King Charles I in 1648 shortly before his execution.
Layered Defences: It is one of the few forts where you can see distinct defensive layers from the 16th, 19th, and 20th centuries in one place.
Lighthouse Count: It is unique for having two lighthouses within its walls and a third just outside on the spit.

Benefits of specific activities
Taking the Ferry: Choosing the Hurst Castle Ferry from Keyhaven provides a scenic boat trip through Keyhaven River, perfect for spotting local wildlife.
Walking the Spit: The 2-mile walk along the shingle spit is great for “working off energy” and offers unique coastal views, though sturdy footwear is essential.
Heritage Membership: Entry is free for English Heritage members, making it a cost-effective day out for those with a pass (though ferry charges still apply).
