On the opposite side of the Square at the corner of Basaričekova Street lies the St. Mark's parish office. The house has been standing there since the 16th century, although it underwent reconstruction in the 18th century and had an extension added in the 19th century. At the west end of St. Mark's Square, the mansion called "Banski dvori", the former residence of the Civil Governor of Croatia (), was built at the beginning of the 19th century and yet, it can be classed among the Zagreb antiquities. "Banski dvori", along with the Baroque mansion beside it, is the seat of the Government of the Republic of Croatia. Since 1734, the Croatian Parliament has taken up the east side of St. Mark's Square.
