Ostuni - Puglia's White City

For the most fabulous photos of Ostuni, click on this website, it's a lovely city, easily reachable by train from Polignano a Mare station, although the walk along the road from the station isn't idyllic,  so it's probably best to catch the bus from the station. Here's a view of the oldest part of the town including the cathedral seen on the right

and a close up of the entrance to the cathedral

in front of the cathedral, there was a lovely roadway with a delightful cafe

Well worth a visit
