Uzeda Door, named after the Viceroy Paceco Francis Duke of Uzeda, is the backdrop to the jewels overlooking Piazza Duomo and, like the other buildings that surround it, is Baroque. Connect the Seminary of the Clerics with the Archbishop's Palace and the Cathedral of Sant'Agata. Built in 1500 and in 1696 became the official entrance to the city, while in the second half of the eighteenth century it was embellished and decorated with precious ornaments. Like many of the other works in Catania, the material that stands out in buildings is undoubtedly the lava stone combined with polychrome marble white. Uzeda Door closes the long and straight Etnea and connects Piazza del Duomo with the harbor area. Outside the door are the remains of the ancient ramparts and baroque facades of the Archbishop's Palace and the Palace of Biscari. Today is one of the most visited tourism destinations in the city.
