The Royal Citadel was the most important English defence for over 100 years with its 70 foot high walls. It was built in 1665 over the earlier Plymouth Fort as a defense against a threatened Dutch invasion. It has been regularly strengthened over the years, particularly during the 1750's when it was equipped with 113 guns, and is still in use today by the military. Guided tours March - September.
On its south east corner it incorporates Fisher's Nose Blockhouse dating from 1490-1540. On the opposite bank to Fisher's Nose was Queen Anne's Battery dating from 1667.
By the end of the 17th century the emphasis on defence changed due to developments in armaments from a central defensive unit to new forts and gun batteries in a ring around the Dockyard and the approaches to it.
