Cathedral of the Virgin Mary, Minsk
One of first church I saw in Minsk was beautiful church with two towers incorporate in huge read-brick soviet architecture. I found out that this is Cathedral of the Holy Name of Mary (Belarusian: Архікатэдральны касцёл Імя Найсвяцейшай Панны Марыі). This is Roman Catholic baroque cathedral. Near is a City hall.
It was completed in 1710 and it belongs to the Jesuit order.
Belarus has quite big population Catholics, in some small cities two churches stand - Orthodox and Catholic. This one Catholic church was built by Jesuits in 1700 - 1710. At 20th century it was restored a few times. In the 1950's two towers of church were demolished and only not so long ago rebuilt again.
It is nice composition both with Town Hall.
Along the Lenin street, just facing the Town Hall and the orthodox Cathedral, lies, between two palaces, the Catholic cathedral of the Name of the Blessed Virgin Mary. You can see just the facade of this 18th century church from the Lenina street, but walking around some nice side street you can see it better and also from the other three sides! :) It's probably mainly used by Polish catholics these days.
