Italy
Atrani perches on a viaduct, wide enough to be a small park. From the balustrade at the back of it you can see straight down to the town’s piazza. Around the piazza the houses cram, piled on each other, a dense mass threaded by passages and arches and many flights of steps — but no streets, except one. Walk through the nearby tunnel and you’ll emerge in another town, the larger and more famous, Amalfi!
