Pavia Cathedral is a church in Pavia, Italy, the largest in the city and seat of the Diocese of Pavia. The construction was begun in the 15th century on the site of two pre-existing Romanesque, "twin" cathedrals. The cathedral houses the remains of St. Sirus, first Bishop of Pavia, and a thorn purported to be from the Crown of Thorns worn by Christ. The marble facing of the exterior was never completed.
The Civic Tower, known in 1330 and enlarged in 1583, formerly stood next to the cathedral. It collapsed on March 17, 1989.
