This part of the island is known both for its natural beauty, with lovely sandy beaches and nature reserves and also for its historical importance. The city of Syracuse under the ancient Greeks was the most important city in the western world. Its collection of monuments including Greek theatre and the island of Ortigia are impressive. The towns of the Val di Noto; Ragusa, Scicli, Modica and Noto together form a UNESCO World Heritage site, listed for its flamboyant baroque architecture. The towns will also be recognised by many as the setting for the Inspector Montalbano TV detective series shown recently on BBC4.
