The baroque tower adjacent to St Nicholas Church was built by multiple architects, mainly Kryštof and Kilián Ignác Dientzenhofer. It was completed by Anselmo Lurago according to the original plans in 1755. The tower’s height is the same as the adjacent cupola and the gallery, which is open to the public, is 65m tall and has 299 steps. The tower belonged to the community, not the church, as indicated by the Malá Strana symbol over the entrance. This is the reason its street address is 556, since churches for the most part do not have numbered addresses. The tower has a separate entrance from the square.
