With its horse-drawn carriages, palace and street entertainers, this stately baroque square is the Salzburg of a thousand postcards. Its centrepiece is the Residenzbrunnen , an enormous marble fountain ringed by four water-spouting horses and topped by a conch shell–bearing Triton. The plaza is the late-16th-century vision of Prince-Archbishop Wolf Dietrich von Raitenau who, inspired by Rome, enlisted Italian architect Vincenzo Scamozzi.
