Corso Umberto, Taormina’s main street, ends at the 1400 city gate, Porta Catania, emblazoned with the Aragon coat-of-arms. Near it stands the three-storied Palazzo Duca di Santo Stéfano, built at the same time as Porta Catania.
It is easy to recognize because of its Gothic windows, fish-tail crenellations, and detailed stonework along the top. Concerts are held in the Great Hall, and two rooms display works by the sculptor Giuseppe Mazzullo (1913-88).
