Topcliffe Castle (also known as Maiden's Bower) is an abandoned castle located near the village of Topcliffe, North Yorkshire, England.

[1] The castle was built at the junction of the River Swale and Cod Beck.

Archbishop Geoffrey of York re-fortified the castle in 1173 during the revolt of 1173-74, with William de Stuteville appointed as governor.

[4] Edward III of England spent a few hours resting at the castle in August 1333.

In 1489, on the site of the castle, Henry Percy, 4th Earl of Northumberland was slain by an angry mob in regard to higher taxation.
