The Church of the Ascension was built in 1729 on the site of a previous wooden church mentioned in the Census Book of 1574. In 1788, during the development of the city's master plan, it became one of the key elements around which the main streets, Moscow and Kasimovskaya, were designed. These streets differed from others by their width of 12 fathoms, while other streets were 10 fathoms wide. The church, elegant in its proportions, resembles the Nikolskaya-Naberezhnaya. The corners of the building are adorned with bundles of three columns, with the corner columns having a larger diameter. Above the white stone capitals is a cornice with a frieze of brick teeth. The vault is decorated with an attic featuring three semicircular arches, the corners of which are reinforced with pilasters. On the hipped roof, five bulbous domes are placed on slender necks, while the round drums stand on semicircular kokoshniks. The domes of the Church of the Ascension are spaced apart, unlike the closely arranged domes of the Nikolskaya-Naberezhnaya church. The corner domes descend to the edges of the roof and resemble the domes of Suzdal churches. On the second tier of the southern facade, there are two windows with carved frames similar to those of the Nikolskaya-Naberezhnaya church. On the western side, a refectory with three low windows adjoins the main volume, the frames of which resemble those of the main building. The pediments above the windows are massive and rest on a cornice of brick teeth. It is possible that the refectory of the Nikolskaya-Naberezhnaya church had a similar shape before reconstruction. A tent-shaped bell tower adjoined the western side of the refectory, its architecture resembling that of the bell tower of the Nikolskaya-Naberezhnaya church. The square of the bell tower, divided by a cornice into two tiers, serves as a vestibule at the entrance from the west. The corners of the square are decorated with pilasters, with the pilasters of the first tier being wider than those of the second. The octagon, equal in height to the square, consists of eight pylons connected by semicircular arches. The bell tower's platform is enclosed by a stone balustrade, and the octagonal tent is topped with a bulbous dome. Soon after its construction, the Entrance to Jerusalem chapel was added to the northern side of the church, which was expanded in 1809 and a third chapel was added in 1892. Time has not spared the church: the domes, decorative attic, window frames, and bell tower were destroyed. Despite this, the church has retained its significance in the urban ensemble. Restoration began in 1999 when the abbot Kirill Epifanov prepared one of the chapels for consecration. By 2000, significant restoration work had been carried out. In 2013, with the formation of the Murom diocese, the church was granted the status of a cathedral.
