Aragonese domination period. The south flank, overlooking Victoria, was re-constructed under the Knights of St. John, namely between 1599 and 1603, after Ottomans invaded the city in 1551. The massive defensive stone walls of the fortifications rise above the town and were built by the Knights to protect the village communities from foraging corsairs attempting to take slaves and threatened invasion of Moslem forces fighting Christendom. Within its walls lies a fine 17th century baroque Cathedral designed by Lorenzo Gafà, the Maltese architect who also built the Cathedral of Mdina. It is said that it lies on the site where a Roman temple dedicated to Juno once stood. It is most famous for the remarkable trompe-l'œil painting on its ceiling, which depicts the interior of a dome that was never built. St George's Parish St. George's Basilica, Malta, which covers the whole of Victoria, caters for a little over half of the population of Victoria, as it is a personal parish (as opposed to other parishes who are territorial) operating in the city of Victoria. Its parish church dedicated to St George has the status of a Basilica. This church was built in the 1670s and suffered severe damage in the earthquake of 1693. A new façade was built in 1818. The dome and the aisles are of recent construction (1930s and 1940s). There are several works of art in this church which include the painting of the dome and ceiling by Gian Battista Conti of Rome and other paintings and sculptures by Mattia Preti, Giuseppe d'Arena, Stefano Erardi, Alessio Erardi, Francesco V. Zahra, Giuseppe Calì, and contemporary Alfred Camilleri Cauchi and John L. Grima. The titular statue of St George was carved from solid wood by Pietro Paolo Azzopardi in 1838 and is the first titular statue on the island. The area over which the church is built is of considerable archaeological interest. The parish celebrates two feasts during the year: 23 April, the official date celebrating the death of the martyr, and the third Sunday of July, when the solemn festivities in honour of Gozo's patron saint are held. In February 2013, the Basilica opened the doors to its new modern museum, one of a kind in the country. It is the first building built for the purpose of a museum. The Museum and cultural centre, named as Heart of Gozo: Il-Hagar, displays a rich collection of historical
