The tower, bell tower/watchtower adjacent to the church of St Nicholas was completed in 1755 by Anselmo Lurago. The tower has always been owned by the municipality, not the Church, and so we can also find a house number above its entrance portal, unusually for a church building. The last watchman, whose task was to ring the bell during a fire and to show from the gallery the direction where the fire was spreading by hanging a red streamer (at night with a lantern) moved away only in 1891. Subsequently, the painter Jan Vochoč, who was a very close friend of Alphonse Mucha, lived here. They even shared a studio in Paris for some time, and when Vochoč married Magdalena Kozáková in France, Mucha was his best man.
