Podřipské Museum features a permanent expositon on the history and the present times of Roudnice nad Labem, but there is also a unique exhibition to be seen called "Mechanical Říp". 42,000 nuts and 32,000 parts from 55 sets of Merkur building blocks have been used to make the movable diorama come alive. The Mechanical Říp exhibition is complemented with an ornithology exhibition.
