It houses some of the most valuable monuments of Timișoara: the two cathedrals, one Roman Catholic and one Serbian Orthodox, the Baroque Palace, the Plague Column, etc.

Until 1716, the current square was crossed diagonally, from the southeastern to the northwestern corner, by the entrenchment of the Turkish fortress.

[3] The idea of creating a rectangular square in the northern part of the fortress was first circulated in 1733.

Prior to these years, it was decided to expand the square to the west, becoming the largest of the fortress squares: 150 × 100 m.[4] The relocation of the seat of the Catholic Diocese of Cenad, from Szeged to Timișoara, made it necessary to build a cathedral for the diocese.

[5] The building of the old Prefecture (the current Baroque Palace) was built in 1754, being initially the seat of the civil governors of Banat.
