Garrison Walls

With a history that spans 350 years, the defences of the Garrison on St Mary’s, Isles of Scilly, form one of the most remarkable and impressive coastal defence systems in England.

You can enjoy a two-hour walk alongside the ramparts of these defensive walls and earthworks, dating from the 16th to 18th centuries.

Other remains include Elizabethan Star Castle and defences from both World Wars.

The Garrison Walls span 350 years: the first stretch of curtain wall, built after the defeat of the Spanish Armada in 1588, was rebuilt and extended around the headland in the 18th century, and the fortifications here were still being put to military use during the Second World War.
