Troitsky Markov Monastery, Orthodox monastery in Vitebsk, Belarus.

The Troitsky Markov Monastery is an Orthodox religious community located in Vitebsk on grounds that today sit near industrial areas. The Kazan Cathedral, built of stone in 1760, forms the central structure with traditional Orthodox architectural features.

The monastery is thought to date from the 14th–15th centuries, when, according to legend, a man named Mark built a chapel on his land and was joined by followers. It was abolished in 1576 and revived in 1633 by Duke Lev Oginski. Closed again in 1920, it was revived on 23 November 2000.

The monastery is named after the legendary hermit Mark, who is said to have built a chapel on the site. The main altar of the Kazan Church is dedicated to the Kazan Icon of the Mother of God, while a side chapel honours St Sergius of Radonezh. A silver-framed copy of the Kazan Icon was returned to the church in 2000.

The monastery stands on an industrial site in Vitebsk, surrounded by factory buildings, so approach it from the city centre by public transport and look for the church among the workshops. The Kazan Church, the only building to survive the 1920 demolitions, is the one structure to seek out; the monastery was revived here on 23 November 2000.

The Kazan church that stands today was built in 1760 to house the Kazan Virgin icon, and it was the only church in Vitebsk that remained open throughout the Soviet era. The monastery was revived on 23 November 2000, when the icon in a silver riza was returned to it.
