Mosta Rotunda, a magnificent Roman Catholic church in Malta, is famed for its colossal unsupported dome, one of the largest in the world, and its survival of a direct hit by an unexploded WWII bomb (a replica is on display). Easily accessible by public transport from various parts of Malta, visitors can explore the church independently or opt for an audio guide or a guided tour for deeper insights into its history and architecture. Entry to the main church is typically free, though a small fee (a few Euros) might apply for access to its museum, crypt, or observation deck. A respectful dress code (covered shoulders and knees) is required as it's an active place of worship. Most visits last between 30 minutes to an hour, extending to 1.5 hours if including the museum. While generally open year-round, it's advisable to check opening hours, especially around religious services, and be aware that accessibility for wheelchairs might be limited due to steps at the entrance.
