In Unirii Square, at the intersection with Iuliu Maniu Street, we find two buildings unique in Transylvania, which impress by being almost symmetrical. From here their name, due to the mirror effect created by them.
Around the church of Saint Michael, until the end of the 19th century, there were houses with shops belonging to the catholic church. Due to the unsightliness of these buildings, the municipality demolished them, compensating the church. In their place, in 1898, the most elegant palaces in the 19th century Cluj began to be built.
The buildings architecture is inspired by the works of the architect Hausmann, the one who restructured the city of Paris in the 19th century.
