2 Best Sights in Mdina and Rabat, Malta

Catacombs run under much of Rabat. Up Saint Agatha Street from Parish Square, the Catacombs of St. Paul are clean of bones but full of carved-out burial troughs and feature the most comprehensive information on the rituals of the city's underground world, including why each tomb is a different shape. St. Agatha's Crypt and Catacombs, farther up the street, were beautifully frescoed between 1200 and 1480, then defaced by Turks in 1551. Back on the square lies arguably the most impressive surviving tunnel area, the Wignacourt Complex, which includes St. Paul's Grotto—believed to be the site where the apostle St. Paul lived during his time in Malta. This labyrinthine network of burial chambers here dates from Punic times and holds one surprise: just below it is a series of World War II bomb shelters (some 50 rooms) carved by hand from an existing water cistern dug centuries earlier by the Knights of the Order of St. John. The Wignacourt museum upstairs houses reliquaries, relics, and paintings by Mattia Preti.

Mdina's St. Paul's Cathedral is famed for Mattia Preti's intricate 17th-century apse mural The Shipwreck of St. Paul. It along with the 900-year-old Irish bogwood sacristy doors were among the few surviving relics of the 1693 earthquake, which destroyed the Norman-era church that stood previously on this site. Rebuilt in the baroque style in 1703, its interior is second only in Malta to Valletta's Co-Cathedral in terms of grandeur, its floor similarly lined with the marble tombstones of Maltese nobles. Across the square lies the Cathedral Museum, set inside a former seminary. It is home to an excellent art collection, the highlight of which are a series of Dürer woodcuts and illuminated manuscripts.
