This very well arranged museum was recently renovated to receive the latest interactive installations. It stands near the place where the naval college of Captain Cook was and discovers his youth, his naval career, his journeys to Canada and Australia, and his three journeys across the Pacific, from 1768-1789.

This complex of gritstone units, which used to be industrial workshops, has been converted into a crafts, science and history centre. Interactive displays illustrate the principles of energy and technology. Ceramics and furniture are made and sold in the craft workshops. The Living History Centre explores life above and below stairs in times gone by.

A Citadel in grey brick and marble built on the riverbank dominated by the hall of steel a glass keep 30 metres high, the museum has housed since 1996 on six floors, a part of the armorial collection formerly in the Tower of London. The vast galleries are devoted to War, hunting, tournaments, Defence and to the weapons of Asia.

The closest cave to Castleton is Peak Cavern, with an impressive entrance situated at the foot of the hill where the castle stands. For three centuries, until 1974, ropemakers lived here, their houses built at the entrance leading to the cavern. There are still lines of black soot from their chimneys at the top of the cavern.
