Ioannovsky Convent, Orthodox monastery on Karpovka River, Saint Petersburg, Russia.

Ioannovsky Convent stands on the Karpovka River Embankment, its main church built in 1902 to a Neo-Byzantine design by diocesan architect Nikolay Nikonov. The grey and brown brick building has dark grey stone lower floors with rows of arched windows, and above rises a tiered structure with five dark domes on octagonal drums, one large central cupola surrounded by four smaller ones, each topped with a cross.

Saint John of Kronstadt established this monastery in 1900, shortly before his tomb became a pilgrimage site within the complex. Authorities closed the buildings in the 1920s, and the Orthodox Church regained possession in 1989.

The monastery holds religious services in the Church of the Twelve Apostles, maintaining Russian Orthodox traditions through daily prayer cycles and liturgical ceremonies.

The convent stands on the Karpovka River Embankment in the Petrogradsky District. Services are held daily: the liturgy at 8:20 on weekdays and at 9:00 on Sundays and feast days, with evening services at 17:00. A moleben to Saint John of Kronstadt follows the liturgy almost every day in the tomb church.

The marble tomb of Saint John of Kronstadt stands in the basement church, consecrated in 1908 to the Prophet Elijah and Tsaritsa Theodora, his parents' patron saints. In 1926 the relics were hidden under the floor and the entrance walled up; they have never been recovered, and the stone tomb now marks the probable site. Twelve healings were recorded at the tomb in 1909 alone.
