Gaze at the masterpieces of the Vatican or walk into the past with visits to ancient relics, historic monuments and legendary museums. Or people-watch while sipping on an espresso in a quaint cafe.

The history of Salerno is as rich and vibrant as its surrounding landscapes. The site of ancient settlements (Neolithic mummy remains discovered here), Salerno has been home to vast empires and was the site of Medieval Europe's first medical school. A trip to Salerno makes it easy to understand why countless people have been drawn to its location along the Gulf of Salerno. Nestled between the mountains and the sea at the southeastern point of the famed Amalfi Coast, Salerno boasts sun-drenched beaches, nature reserves and parks, historic sites and delicious local cuisine.

The ancient port city of Catania is situated in the shadow of the famous active volcano, Mount Etna, which dominates the landscape and is intertwined with the town's history.

You can also journey outside Catania to explore the surrounding lava fields and unique rock formations or hike, bike or go off-roading on one of the trails crisscrossing the volcano for an unforgettable outdoor adventure.

Although somewhat scarred by World War II, Valletta prides itself on its magnificent Baroque palaces, piazzas, gardens and churches. The Magisterial Palace, built between 1571 and 1574, now houses the Maltese Parliament and offices of the President of Malta.
