Mologa, a city located at the confluence of the Mologa River and the Volga, was submerged during the creation of the Rybinsk Reservoir. This city housed a monastery and several churches.

The Afanasevsky Monastery, originally a men's monastery since the 15th century, became a women's monastery in 1795. It was located 500 meters from the city and included four churches: a cold church built in 1840, and three warm churches erected in 1788, 1826, and 1890. The main shrine of the monastery was the miraculous icon of the Theotokos of Tikhvin, dating back to the early 14th century.

The Resurrection Cathedral, built in 1767 in the Naryshkin style, was renovated by merchant P.M. Podosenov between 1881 and 1886. The cathedral had five altars: the main one for the Resurrection of Christ, as well as side altars for the Prophet Elijah, St. Nicholas the Wonderworker, the Dormition of the Theotokos, and Saints Athanasius and Cyril. The bell tower, consisting of three diminishing octagons, was built after the model of the Uglich bell towers.

Separate from this cathedral, a warm Epiphany Cathedral in the Russian-Byzantine style was erected in 1882. It had three altars: for the Epiphany, the Protection of the Theotokos, and St. Nicholas the Wonderworker. The construction was actively participated in by P.M. Podosenov and merchant N.S. Utin. The cathedral also included a wooden, plastered on both sides Exaltation of the Holy Cross Church, built in 1778 at the cemetery.

The Ascension Parish Church was built in 1756 and had three altars: for the Ascension, Saints Boris and Gleb, and Archangel Michael. Its facades featured elements of Baroque style.

The All Saints Cemetery Church, erected in 1805, had two altars: in the name of All Saints and John the Baptist.
