Portland Castle
Portland Castle is a Henrician artillery fort on the Isle of Portland built between 1539 and 1541 to guard the Portland Roads anchorage. The fan-shaped keep of ashlar Portland stone with a curved central tower, angular side wings and a forward gun battery sits within a rectangular walled courtyard alongside a small attached house known as the Captain's House.

As it stood in 1541
The shape it held in its prime.
A low, fan-shaped stone keep about 120 feet across, built of pale ashlar Portland stone with a rounded central tower flanked by two angular wings and a forward curved gun battery with regular ground-floor embrasures; the keep has rounded parapets and a generally two-storey profile. The keep faces directly onto the sheltered anchorage at the shore, set within a walled courtyard roughly 170 by 90 feet, with a two‑storey Captain's House on the west side and gun platforms to either side of the keep. Traces of a surrounding moat and drawbridge slots are visible in the stonework.
