Montezara, which rises in the territory of the municipality of Monastir, is a hill of volcanic origin that reaches 230 meters above sea level. On its slopes there lies an ancient necropolis, dating back to 3000 BC. There, a great number of domus de janas were unearthed (those are known as houses of the fairies or houses of the Janas people).
In reality these are not houses, but tombs dug in the rock, burials designed to accommodate not only the dead but also their personal items, furnishings, weapons and food supplies.
The earliest settlements in the area date back to the Neolithic period, but the many findings inform us that even in the Nuragic, Punic and Roman ages, this territory continued to be populated later on.
On the mountain’s northern side, we find the so-called "eyes of the mountain". These domus are in fact dug very close one to the other; similar to open eyes looking on the valley below, these gauges are visible also from the highway road; they are called is ogus de su monti.
On top of Montezara there is a hidden Nuragic sacred area; on the western side, a village consisting of circular and rectangular huts was discovered, Bia’e Monti.
