Built between 1787 and 1789, the Porter Pia Gate gave the city a monumental coastal entryway, as per the wishes of Pope Pius VI (1829-1830) after completion of the Lazzaretto.
The Istrian stone facing the sea is richer in detail than the tufa-stone ashlar work facing the town. The Gate designed by Filippo Marchionni’s son, Carlo has preserved its Baroque style as well as the impressive grander underlying its dual symbolic function as both a juncture and a defensive stronghold at the entry point of the city.
