The Baroque interior of St. John's Cathedral is amazing. There is a Cathedral Museum, which displays two important works of the Italian painter Caravaggio.
St. John's Cathedral in Valletta can definitely be described as brilliant in gold. When you enter the cathedral, you can see the golden color. The whole cathedral is covered with gold foil, which shows the degree of luxury. The Mass here is solemn and solemn, and there are many believers. It's absolutely worth visiting.
