Building: this Cathedral was founded
after two previous churches on the same site were destroyed
in an earthquake. The construction began in 1117. The church
was inaugurated on September 13, 1187. Since then, there have
been some renovations, but the whole of the original construction
plan remained intact. The current interior dates from the
15th century. The impressive bell tower, which was never fully
finished, was built in the 16th century, designed by the Venetian
architect Michele Sanmicheli.
