Portland Castle is a mid-sixteenth-century artillery fortification built on the Isle of Portland in Dorset under the direction of King Henry VIII. The castle was constructed between 1539 and 1542 as part of Henry's wider programme of coastal defence against potential invasion from France and Spain, and exemplifies the revolutionary design of low, angular bastions characteristic of early modern military architecture. The structure comprises a central circular keep surrounded by lower gun platforms, allowing for comprehensive coverage of Portland Harbour and the surrounding waters. The castle remains substantially intact and serves as an important surviving example of Tudor military engineering.
