This stunning 1895 neo-Byzantine church was built by architect Vasily Kosyakov on the site of a former monastery. It was closed during the Soviet period, and from 1957 the building became the city’s first – and very popular – year-round skating rink. The 7.7m, 861kg metal cross on the roof was only replaced in 1998. Following a wonderful renovation, the church is looking superb again; do go inside to see the murals and icons covering the interior.
