The city of Brindisi, located on the Adriatic coast, lies between two deep bays linked to the open sea by a narrow and deep channel, overlooked by the Castello Rosso (Red Castle), named for the particular color of the stone used to build it. The Swabian Castle, rather, overlooks the western channel of the port and today is a venue for major cultural events. Among the sights not to be missed, the Church of San Giovanni al Sepolcro, with a beautiful and finely-decorated marble portal, and the Colonna Romana (Roman Column), once flanked by a “twin” that today is part of the structure of the famous Colonna di Sant’Oronzo (Column of St. Orontius) in Lecce. The beautiful city of Ostuni stands out against the intense green of the olive trees, with the whitewashed old town crossed by a maze of alleys and courtyards, low houses and narrow passagways that are overlooked by the majestic Cathedral. Beautiful sandy beaches are scattered along the coast, lapped by the clear water of the Adriatic Sea;  colorful patches of the Mediterranean brush and the plantlife of the seabeds contrast with sometimes sandy, sometimes rocky shores. To the north of Ostuni lies one of the most interesting natural areas in the region: the WWF Oasis of Torre Guaceto. The seawater rushes in toward the cliffs with its scrub, dunes and expanses of reed beds. This territory serves as an ideal habitat for snipes, wild ducks, nightingales and amphibian species, as well as for marine plant species, including meadows of Neptune Grass, sea fans and coral.
