Across the Grand Harbour, to the south of Valletta, are the historic fortified towns of Vittoriosa, Cospicua and Senglea, commonly referred to as the three cities of Cottonera. If you only have time for one of them, Vittoriosa is the one most worth a visit. Here you'll find Fort St Angelo, the Inquisitor's Palace, and the Vittoriosa waterfront, which was refurbished in the early 2000s to once again reach up to its former glory.

The Pasha Gardens is a little-known gem near the old town of Thessaloniki. Half-demolished whimsical ruins are spread across the garden, granting it an air of mystery. It is no surprise that numerous myths and fables have stemmed from here. The park's imaginative, Gaudí-esque architecture centres around an ornate fountain encircled by a tunnel leading nowhere.

The White Tower is the most iconic symbol of the city. The tower was constructed by the Ottomans sometime in the early 15th century and once guarded the eastern end of the city's sea walls. In the 19th century, this tower was used as a notorious prison. Nowadays, it is a welcoming museum of art and local history. The museum offers a rapid lesson in the history of the city. Ideally, you'll take in this well-dosed overview before continuing to the more specialised museums and archaeological sites. For best results, grab the free audio guide at the entrance. The last floor of the tower gives you a wonderful view of the city.

The Xiqu Centre building, inspired by the design of traditional Chinese lanterns, seems to invite you inside with its facade resembling a futuristic interpretation of stage curtains opening. 1,073 guests can enjoy Xiqu exhibitions and the traditional Chinese opera in the Grand Theatre, while the Tea House Theatre holds 200 seats. Guided tours in different languages can also be booked.
