Originally built as a merchant's house overlooking the medieval quayside, it later became part of the town's coastal defences following the French raid of 1338.

Over the centuries, the chapel has welcomed different communities, including French Protestant worshippers who used the building from the 16th century until the Second World War, earning it the nickname ‘The French Church’.

The West Gate

Over the centuries, the gate has witnessed some of the most significant moments in Southampton’s history. It was the route taken by Henry V’s army as they left the city for the Battle of Agincourt in 1415, and later the departure point for the Pilgrim Fathers as they set sail aboard the Mayflower in 1620.
