The Royal Citadel in Plymouth, designed by Sir Bernard de Gomme and built in the late 1660s, is a dramatic English Baroque fortress overlooking Plymouth Sound at the eastern end of Plymouth Hoe. Originally constructed to defend the coast during the Dutch Wars and to monitor the recently rebellious town, the citadel features 70-foot-high walls and a distinctive Portland stone gateway accessed via a drawbridge over a dry moat. Still functioning as a military base housing the 29th Commando Regiment Royal Artillery, visitors can explore the ramparts via guided tours offering panoramic views across Plymouth Sound and beyond.
