After breakfast on board, guests who wish may join the optional Mosta & Valletta & Mdina & Marsaxlokk tour organised by the ship. Our first stop is Mosta, where we visit the Basilica of Santa Maria Assunta, which has the third-largest dome in Europe. The interior paintings of this vast basilica, whose dome has an external diameter of 56,2 metres, are primarily the work of painter Giuseppe Cali. We will see a replica of the 200 kg bomb dropped by Nazi German aircraft in 1942 during World War 2, which pierced the dome and lodged in the church floor without exploding, and learn about the church's interior and exterior architecture. We then visit Malta's former capital, Mdina, which served as a filming location for many scenes in the renowned series Game of Thrones. As we explore the narrow streets of this medieval town, known as the Silent City, we will see the magnificent Saint Paul's Cathedral, the 13th-century Falson Mansion built by the noble Maltese Falson family, the 17th-century Baroque Carmelite Monastery, Vilhena Palace and Mdina's historic houses. We continue our tour with a visit to the fishing village of Marsaxlokk. Do not miss the picturesque sight of the charming little fishing boats known as Luzzo, with their distinctive Maltese colours and designs. This lovely fishing village also hosts an open-air market. We will have free time here, allowing guests who wish to enjoy lunch at local restaurants serving fresh fish and seafood. After our free time, we depart for Valletta for our city tour. Valletta was selected as the European Capital of Culture for 2018 by the Council of Ministers of the European Union. During our tour, we will have the opportunity to view the city and its magnificent fortifications from the outside. Following our coach tour, we will explore the lively streets of the capital, Valletta, on a guided walk. Our first stop will be the Barracca Gardens, built on the upper section of the defensive walls surrounding this impressive city. Created by the Knights of St. John, these gardens also offer magnificent views of the Grand Harbour and the 3 old fortified cities. At the end of our tour, we return to the ship. Dinner and overnight stay on board.
