Cathedral of the Holy Spirit
The Cathedral of the Holy Spirit was built between 1633 and 1642. At the time of its construction, the building belonged to a Catholic monastery in Bernardines. It was only in 1860 that the church was converted to Orthodox worship, and shortly afterwards an Orthodox monastery was inaugurated there in 1870. However, the monastic community was dispersed by the Bolshevik authorities in 1922. The church is now an Orthodox cathedral.
