There are four small museums in the Citadel run by Heritage Malta. Entry to all four is covered by a joint ticket. Alternatively if you are planning to visit Ggantija Temple, Ta’Kola windmill and sites on Malta, a 30 day pass may be better value. This gives free entry to all Heritage Malta site (except the Hypogeum) for €30 or €22 for senior citizens. We didn’t visit the Natural History Museum. I have written separate reviews for each of the museums.
The Archaeology Museum is in a new building near the Cathedral. It is a fascinating small museum covering the period from prehistoric times to the late medieval period. There is plenty of information in English and Maltese. The ground floor has an introduction to prehistory with information on landscape and farming. There is a lovely small pot sherd with five birds etched on it.
Upstairs there are several display rooms. The prehistory gallery had finds from Xaghra stone circle including some small carvings of fat ladies, including one of two headless sitting figures with one holding a baby. There are also examples of beautifully carved ‘stick’ figures with an animal, bowl and bird. There is a large display room covering Punic and Roman times with stone sacrophagi, cremation urns, oil lamps and pottery. A third room has artifacts from shipwrecks including anchors and clay amphorae. Downstairs in the final room is a Medieval display with a painting showing what the citadel looked like in 1530, as well as tombstones, clay lanterns etc.
