Originally called Porta Comerda, it was given the name Porta imeriale by the people, since every emperor entered the city through this gate. First built in the late 15th century as part of the city's defences, it was stylistically modified in the 16th century to give it its current appearance. Nice sight when you are here.
In truth, in ancient times Porta Imperiale was called Porta COLMEDA and not as erroneously written above "Porta Come..da", but it still brings joy...a poetic license
Porta Imperiale allows entry to the citadel from the west on via Mezzaterra. Formerly called Porta Cormeda, tradition has it that it took on its current name of Imperiale because the emperors, from Frederick II to Charles IV, passed through there on their visits to the city.
Since 1876 it has also been called Porta Castaldi in honor of Panfilo Castaldi from Feltre, one of the first Italian printers.
Built in 1489, under the mayor Girolamo Cappello, it was renovated in "classical" forms in 1545, losing any defensive content
