The Royal Citadel in Plymouth, Devon, England, was built in the late 1660s to the design of Sir Bernard de Gomme. It is at the eastern end of Plymouth Hoe overlooking Plymouth Sound, and encompasses the site of the earlier fort that had been built in the time of Sir Francis Drake. Fisher's Nose Blockhouse, located on its south east corner, dates from 1490–1540 and was intended to protect the Cattewater. On the opposite bank to Fisher's Nose is the Queen Anne's Battery, dating from 1667.
