The Kergensky Blagoveshchensky Monastery was founded in 1814 and existed until 1923. Its founder was monk Tarasiy, who at the age of 27 established the Blagoveshchensky Kergensky skete on the right bank of the Kergenez River in the Semyonov district of the Nizhny Novgorod province. Although there were already Old Believer sketes in the area, the Blagoveshchensky skete quickly became well-known and attracted many Old Believer monks. In 1848, during the struggle against sectarianism under Nicholas I, the skete was closed by the authorities due to a criminal investigation. Official P.I. Melnikov-Pechersky, who was involved in eradicating the church schism, managed to convince monk Tarasiy to convert to the true faith. In 1849, the skete was reopened as the Kergensky Blagoveshchensky Monastery of the True Faith, and its first abbot was Tarasiy. Some of the brotherhood also accepted the true faith, but many monks dispersed to other sketes. Under abbots Tarasiy and his successor Evgeniy, the monastery developed and prospered, but under subsequent leaders, it fell into decline, especially after losing the flood meadows along the Kergenez.

By the end of the 19th century, the monastery had three churches and 25 monks. After the death of the last abbot, Archimandrite Filaret, unrest began in the monastery, and the monks dispersed. On May 3, 1908, the monastery was transformed into a women's monastery, and nuns from the Osinovsky Monastery of the True Faith, located 55 versts from Semyonov, moved there. At that time, about a hundred nuns lived in the monastery. The Blagoveshchensky Kergensky skete ceased to exist during the years of Soviet repression against religion.
