The Cathedral Museum holds two works by Caravaggio who was briefly himself a Knight, one of them being his masterpiece the famous huge "Beheading of St. John the Baptist."
The Palace of the Grand Masters now is the President's office and the Maltese parliament. The staterooms, when accessible are quite impressive. It also houses the Knights' armoury which is open to visitors daily from 9am–5pm. (However, all other parts of the palace are closed to visitors, so what they can see is limited.) At the entrance you can receive an audio guide which is included in the entrance fee. It provides you with further historical information about the various armoury of different eras beginning from the medieval chain mail up to the 17th century armour.
The Malta Experience, despite not being entirely cheap (3.5 Liri) visitors who have any interest in culture or history and who haven't exhaustively read up on the country before coming here would do well by starting their visit to Malta by going here as it is an excellent introduction to the country. It gives an impression of major events that shaped the country, but as it's only half an hour long and meant for first-time visitors one shouldn't expect an in-depth dry scholarly treatment of the subject.

The Upper Barrakka Gardens at the upper south side of the peninsula offer a jaw dropping view of the Grand Harbour. Go on a sunny day and bring champagne!
The National Museum of Archaeology Even though Malta has an impressive and unique ancient history this museum housed in the former Auberge de Provence in Republic street can be rather a disappointment. The museum is currently partially being renovated hopefully bringing something more worthy of its name. Auberge de Provence, Republic St, Tel: 2122 1623.
