Treviso Cathedral originates from the 6th century and stands in an area where during the Ancient Roman period there were a temple, a theatre and possibly some baths. In the 11th-12th centuries the church was remodelled in Romanesque style. In 1768 it was demolished and rebuilt in Neoclassical style, only the crypt remaining from the previous edifice. The current façade dates from 1836. Treviso Cathedral was involved in the Good Friday bombing of 7 April 1944, having part of its library damaged by fire.
Sights in the interior include the Malchiostro Chapel, designed by Tullio and Antonio Lombardo, which was frescoed by Il Pordenone and which houses the Malchiostro Annunciation by Titian and two canvasses by Paris Bordone.
The church has an unfinished bell tower, whose construction, according to the tradition, was stopped by the Venetian government to prevent it from becoming taller than the campanile of St. Mark's Basilica. The crypt houses the tombs of the city's bishops.
The Diocesan Museum is home to a fresco by Tommaso da Modena.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
