Atrani

The small town of Atrani is wedged in between the sea and the cliffs along the Amalfi Coast of Italy, just east of the town of Amalfi.  We've visited the area three times.  The road carried on the viaduct and around the building on the right is the Amalfi Coast Drive, the only road that goes from start to finish on the coast.  It's barely wide enough for two small cars to pass each other.  To be helpful, they've put mirrors on the corners (you can see one in the picture) as you drive around that big building so you can try to see what's coming at you.  Photo is from Conde Nast Traveler.
