The city is old and in ancient times it was rich and important because of strategic location in the middle of the Mediterranean Sea. However, we only stopped by for a ride on the Ferris wheel at the port (40.923848, 9.506416).
Between these two buildings begins the only tourist street in the city; we walked along it too. The street is cozy, with many restaurants.
In general, there's not much to do here. There are much more interesting villages nearby, that's where you should stay.
