Harry's Walls, Unfinished Tudor fort in St. Mary's, Isles of Scilly, England.
The fortification features two angular bastions connected by a curtain wall constructed from granite blocks measuring 21 meters across and 2.3 meters in height.
Construction of the fort began in 1551 under Edward VI's government to protect St Mary's harbor from French attacks but remained incomplete due to financial limitations.
The fort's design incorporated advanced Italianate-style military architecture, reflecting the Tudor period's adoption of continental European defensive innovations.
Visitors can access the site freely during daylight hours by following an uphill footpath that leads to panoramic views over St Mary's harbor.
A prehistoric standing stone positioned north of the fort serves as a maritime navigation point, with a modern navigational aid installed beside it.
