Ghar Dalam: The Cave, the Museum, and the Garden is a guidebook about what is considered one of Malta's most important national monuments, as it contributed a great deal to our knowledge on life on the Maltese islands in the remote and in the more recent past. Ghar Dalam is the only cave in Malta where one can study the Pleistocene or the Ice Age fauna in an uninterrupted sequence dating back to 180,000 years ago while having the latter all in one place.
