On the pedestrian Bauman street, there is a place from which an incredible view of the central part of Kazan can be seen. This is an observation deck on the bell tower of the Epiphany Cathedral, the tallest ancient building in the city stands 74 metres tall.
According to the Archpriest Alexei Derzhavin - abbot of the cathedral, the bell tower was made up of 2,000,000 bricks. Inside it, the Church of John the Baptist, the patron saint of heaven patron Ivan Krivonosov, was opened. The cathedral as well as the observation deck was closed down in the 1930s, and was only restored in 2016.
