Polruan Blockhouse is a Tudor coastal artillery fortress built during the early sixteenth century on the eastern bank of the River Fowey in Cornwall. Constructed as part of Henry VIII's programme of coastal defence against French and Spanish threats, the blockhouse formed part of a defensive system with Fowey Castle across the river to guard the strategically important harbour. The structure comprises a compact stone-built fortification designed to mount cannon and small arms, reflecting the military engineering standards of the early Tudor period. Its remains survive as a scheduled ancient monument and represent an important example of early modern military architecture in southwest England.
