Plunge deep into Ibiza's ancient civilizations in this annex of the Archaeological Museum, part of old Eivissa's designation as a World Heritage Site, which contains the subterranean burial chambers of some 3,000 tombs dating principally from the Punic and Phoenician periods of occupation (dating to the 7th century BC). Surrounded by olive groves and finally reopening in 2012 after a long closure, it constitutes one of the largest and best-preserved ancient necropolises in the world. In addition to the tombs (about 340 of which can be viewed) are important artifacts such as amulets, weapons, jewelry, and bronze tools.
