Valletta packs an extraordinary amount into a compact fortress city, so prioritizing is essential on a short stay. St. John's Co-Cathedral delivers one of Europe's most opulent baroque interiors, while Fort St. Elmo & National War Museum anchors the peninsula's defensive history at the harbor's edge. A stroll down Republic Street connects the old town's landmarks on foot, and Upper Barrakka Gardens rewards the climb with sweeping views over the Grand Harbour toward The Three Cities. Rounding out the list with a day trip to Mdina or Gozo Island balances the capital's grandeur with Malta's quieter, older character.
