Context

Our verdict

Piran, port town of Slovenia on the Adriatic coast: 4000 inhabitants at the extreme south-west of the country (Slovenia has only 29 miles of coast). Former Venetian possession 1283-1797, preserved Venetian atmosphere with near-intact 13th-18th century architecture ("Slovenian pearl of the Adriatic"), nicknamed " little Venice " despite its modest size.
