Turin's cathedral was built between 1491 and 1498 on the site of three 14th-century basilicas and, before that, a Roman theatre. Plain interior aside, as home to the famous Shroud of Turin (alleged to be the burial cloth in which Jesus' body was wrapped) this is a highly trafficked church. A copy of the cloth is on permanent display to the left of the cathedral altar.
The separate Romanesque-style bell tower looks older than it really is; it was designed by Juvarra and built in 1723. Just to the north lie the remains of a 1st-century Roman amphitheatre , while a little further to the northwest lies Porta Palatina , the red-brick remains of a Roman-era gate.
