Paola is the site of the Hal Saflieni Hypogeum. These three stories of underground chambers, used for religious and burial purposes, were carved out of solid rock over several centuries, beginning in 2400 BC.
Also nearby, at
Tarxien, are impressive 4,000-year-old megalithic monuments and temples. This series of structures consists of stone idols, altars, screens, fireplaces and chambers. Allow at least a half-day to visit both Paola and Tarxien. Tours of the Hypogeum should be booked well in advance, as daily visitor numbers are strictly limited.
