Staircase of the tower

Along with the Hall of Columns, the tower was built between 1482 and 1898, before being extended and having battlements added at a later date. A chapel can be found on the ground floor of the tower, and there are two upper floors which can be reached via a spiral staircase. This staircase is most impressive in the sense that it has no central support to which each step is anchored, meaning that support comes from the connection between each step. Records state that the two upper floors were used as a prison for bankrupt merchants.
