From 1962, the premises of Michael’s Tower hosted the exhibition of arms and city fortifications. In 2020 this exhibition was canceled and a complex restoration of the tower started to be planned as well as the scenario of a new exhibition of the Museum of arms and city fortifications.

Michael’s Tower together with Michael’s Gate used to be a part of medieval city fortifications, which were started in the 13th century, rebuilt on several occasions and tore down after 1775. Originally it was a 15th century polygonal tower, raised in last decades of the next century with an octagonal superstructure. This construction modification employed also stone material from the canceled St. Michael’s Church. Current appearance of the tower originates in the Baroque renovation. In 1758 a copper statue of Archangel Michael with a dragon by Peter Eller was set on its spire. The Gothic chain bridge was substituted with a Baroque one completed with statues of saints, while the defense wall with a zwinger was incorporated into blocks of building of Zámočnícka ulica (Locksmith Street).
