Surrounded by cork oaks, Mediterranean shrubs, olive groves and vineyards, and irrigated by springs, it sits in the south of the basaltic plateau of Abbasanta. Paulilatino, the biggest town of Guilcer in the Medieval period, has 2300 inhabitants, offers uncontaminated scenery and is famous for its prehistoric sites: Domus de Janas, dolmen, menhir and as many as 110 Nuragic sites. The most important of these is the Temple of Santa Cristiana (12-8th century BC), the best preserved and fascinating example of Nuragic holy architecture. It stands in a park with hundred-year-old olive trees that takes its name from the 11th century country Church of Santa Cristina. The Well Temple, surrounded by a fence shaped like a lock, has a vestibule and staircase covered by architraves and a chamber with a tholos vault. Water enters the pool through a year-round spring. Outside the fence, there is a meeting shed and a dozen or so other buildings, possibly housing for priests and market stalls.
