The Cathedral of the Holy Spirit is one of the most visible churches in Minsk, with its central location overlooking the Svisloch river in the historic Upper Town. The Cathedral is the most important Russian Orthodox church in the city. Its origins date back to the 17th century (1633-1642) when the building served as a Catholic Bernardine monastery. After several devastating fires and a conversion to Orthodoxy, the church was expanded and renovated, though the monastery was closed in 1922. The church's holiest icon is the image of the Mother of God, which is said to have been found by Minsk residents in 1500.
