Explore the castle, caponier and ramparts with it's unique design and enjoy panoramic views from the top of the Keep of the Isle of Wight and ships on the Solent. Built in 1544, Southsea Castle was part of a series of fortifications built by King Henry VIII along the Portsmouth coast to protect the country from invaders. This fascinating site is where the king watched his favourite warship, the Ma
ry Rose, tragically capsize and sink in 1545. Southsea Castle is open as a historical attraction free of charge between March and October each year. Visitors can explore the keep, enjoy panoramic views from the top of the Keep to the Isle of Wight and Solent before enjoying a bite to eat in the Courtyard Café (open all year). Purchase a gift or two from the Waterfront Gift shop or some beer to take home from the on-site micro brewery. The Castle's event programme includes family activities and trails, plus for adults, the popular Friday night Champagne Bar from May to September. Please note: Some areas of Southsea Castle may be closed or inaccessible for operational purposes, or in the event of a wedding or other event taking place there. To check if there is an event or wedding taking place in the castle, please phone ahead to enquire which parts of the museum are open. If you require any information for your visit, please contact us.
