King Charles's Castle, Tudor artillery castle on Tresco Island, England
The granite stone castle features a polygonal structure with a gun battery at the front and residential quarters at the back, overlooking New Grimsby Harbour.
Built between 1550 and 1554 during Edward VI's reign, the castle formed part of defensive fortifications against French threats to the Isles of Scilly.
The castle represents Tudor military architecture with its distinctive polygonal design, which appears only in similar structures along the River Thames.
Visitors need sturdy footwear to reach the castle, which sits on Castle Down's highest western point and connects to a six-mile coastal walking trail.
Construction of the castle required 540 oak trees transported from South Wales, demonstrating the scale of resources needed for Tudor military buildings.
