The capital of Malta, Valletta, is home to St. John’s Co-Cathedral, perhaps one of the most marvellous of all Maltese churches. In contrast to some other Baroque buildings, the church’s façade, which was established between 1573 and 1578 by the Order of the Knights Hospitaller, looks to be rather simple. But the opulent inside is where the true spectacle is. The inside of the cathedral, designed by renowned architect Mattia Preti, is embellished with magnificent paintings, fine marble sculptures, and a magnificent marble floor that displays the coats of arms of the knights. When visiting the nation’s capital, exploring this co-cathedral is not only advised but essential!
