The museum was organized in the Clock Tower, a historic monument from the 14th century, restored in the 16th century, and later, in 1678 and 1894. It belongs to the Gate complex giving access to the Fortress. It is 64 m high, with five levels, and open wooden gallery on the last level. The ground floor of the Tower is made up of boulders 2.30 m thick, dating from the 14th century. The tower was damaged by the fire from 1676 and was partially restored, as was the roof, by Baroque masters - Veit Gruber, Philipp Bonge and Valentinus Zimmermann. In 1648 Johan Kirschel of Königsberg added the quarters of hour, and the figurines were restored in 1677.
