Located on a flat area in the centre of Marmilla, by the western edge of a bog, drained at the end of the 19th century. Pauli Arbarei is a town of 600 inhabitants with agro-pastoral traditions, which relied on cereal farming in the past and today boasts quality food and wine products. The area is exalted by a dozen or so Nuragic sites, some of which are yet to be studied; particularly, the three-lobed Nuraghe of Bruncu Mannu. Its fertile countryside is dotted with archaeological sites, with new sites still being discovered: worked stones, half-buried sections of nuraghes and even a triangular well temple hidden among the ruins.
The centre of the town hosts the Parish of San Vincenzo Diacono, built in the 17th century in Renaissance style.
