This 15th-century estuary fort is 6.5km (4 miles) east of the city center at Broughty Ferry, a fishing village that was the terminus for ferries crossing the Firth of Tay until the bridges were built. Besieged by the English in the 16th century and attacked by Cromwell's army under General Monk in the 17th century, it was restored in 1861 as part of Britain's coastal defenses. The museum has displays on local history, arms and armor, seashore life, and Dundee's whaling story. The observation area at the top of the castle provides fine views of the Tay estuary and northeast Fife.
