Polruan Blockhouse

Also known as, or recorded in historical documents as; Polruan Castle

In the civil parish of Lanteglos.
In the historic county of Cornwall (Modern Authority of Cornwall, 1974 county of Cornwall).

Boom tower survives as a two storied rectangular building constructed on a low rocky promontory which juts out into the River Fowey, and is located opposite another boom tower, Fowey Blockhouse. The structure is roofless and is constructed of the local slate stone with moulded granite surrounds to some windows, gun ports and the main entrance. The boom tower was probably built in response to a raid on the town of Fowey by the French in 1457. Leland states that the towers were built during the reign of Edward IV (1461-1483). Polruan Blockhouse was also equipped for use with guns. The two boom towers were designed to have a chain laid across the river between them which could be raised to prevent enemy shipping reaching the town of Fowey. Advances in artillery made the tower obselete and it was superseded by St Catherine's Castle in the 1520s, on the opposite side of the river

This site has been described as a;
Chain Tower / Artillery Fort.

A form of harbour defence where a chain is extended across the entry into a harbour to prevent access by enemy vessels. The mechanism housing the chain and allowing it to be raised and lowered was housed in a defensive tower, often an artillery fort in it's own right.

Fortifications designed specifically for mounting artillery, usually as coastal defence against warships. Vary from large stone structures to small earthwork bulwarks with room for one or two pieces. Although some of the large royal buildings were of high quality with good detail these are actually practical military works.

The confidence that this site is a medieval fortification or palace is Certain.
