Baroque church, constructed in 1747–1754. Length 31.7 m (104 ft). Width 20.4 m (67 ft). Height 50 m (160 ft). Both the external and internal decoration on the church was carried out at the same time. Cast iron floor slabs were delivered from Moscow. Also, forms were made for the church's windows, doors, walls, and for space under the cupola. The planned iconostasis, designed by the Italian architect Rastrelli, was also added. The wood for the iconostasis, altar canopy, pulpit, and tsar's place were carved out in Saint Petersburg in order to save time. The iconostasis' icons were carried out by Petersburg artists. For gilding, 1,028 slabs of gold were used in the interior.
