The Baroque-style Union Square (Domplatz), which appears as a sketch on the 1733 plan, was later finished, but larger in size than specified in the above plan. The unusually large dimensions of the square, compared to the size of the fortress, served to highlight baroque style of this space. The representative buildings located on the four sides of the square offer a suggestive image of the Timișoara architecture from the 18th century, even if over time these buildings have undergone changes. The strong points of this Baroque heritage are the Roman Catholic Dome, on the east side; the Serbian Orthodox Episcopal Cathedral on the west side; The Baroque Palace (headquarters of the Banat Country Administration in the 18th century), on the south side, and the typical 18th-century buildings on the north side of the square.
