 The square is landscaped in an egg-shape, cut in half by the National Highway 13, and is tipped by buildings with long-established national style.The building of the City Hall (1791), located in the north section, dominates the square and is of neoclassical design in the taste of the English settlement in Porto.This English influence is visible in the arches of ashlar masonry on the ground floor, with tiling, to the Portuguese taste, added in 1908-10 by Rocha Peixoto, of the authorship of the Belgian painter Joseph Bialman.
