The Church of the Assumption was designed and built by Lviv’s most noteworthy architect Paolo Dominici Romano, an Italian by birth who headed the construction up to 1597, when it was placed in the hands of his father-in-law wojciech Kapinos. A year later it was taken over by Ambrogio who completed the Church. It is, however, Paolo Romano who deserves the main credit for the work, although the idea of merging the forms of old-Russian architecture with the style of the Renaissance belongs the Stauopegia Fraternity, a staunch adherent of natinal traditions.
The blending of old and new motifs, the remarkable integrity and perfection of the entire structure have made the Church of The Assumption a unique architectural monument.
The church composition is with three cupolas, traditional for local ecclesiastical architecture. On the east the basilica passes into a semi-circular apse, on the west it ends up with a narthex with a gallery, called a “babinets“. A gallery runs along the internal side of the walls. Two pairs of Tuscan-styled columns divide the Church into three naves, the central one being the widest. Each part – the centre, the apse, and the babinets – is topped by a cruciform vault with almost identical cupolas which are built on a single longitudinal axis.
