Walk down the high street of Tropea, away from the railway station and you will eventually walk off a 100-foot cliff--the road simply ends where the floor no longer is.
Tropea, from the seaward side, is an incredible sight. The town is built into and onto a high sandstone promontory, with doors, windows, and bits of old buildings popping out of the sandstone cliffs at random places.
Many of the old buildings that still exist (a fair few have fallen onto the beaches below over the years) were built for religious orders, but these are mostly private homes now. You can only wonder how much these people pay in insurance every year. Especially when you consider that the base of the cliff is home to dozens of shrines to people who have "fallen" off Tropea over the years.
