Spread around the castle and linked via a baffling array of higgledy-piggledy wooden steps and dark, plunging spiral staircases, two main collections can be found inside the western casemates (casements) and the Ducal Palace respectively. The former, made up of 19th-century European glassware, ivory walking stick handles and the like, is the less interesting of the two, although a visit to the latter, including items dug up in the vicinity of the castle, a huge collection of coins and a few life-size models of medieval gents with enormous moustaches, is money well spent.
