In the north-western part of the island, near cala Chiesa, there are the remains of a single-nave medieval church, in Romanesque style dedicated to Saint Pontian.

Around this church it has been possible to identify the remains of a medieval inhabited center and further upstream of a castle, probably the ancient Gurguray even if there is no certain information on its effective demographic consistency.

To the east of cala di Chiesa stands the rock of the dinosaur, a bizarre natural sculpture shaped by the winds and the sea.

On the south coast are the ruins of a lime kiln, produced in the past from the limestone of nearby Tavolara, by burning wood from Molara.

Even the Manx shearwater is present with hundreds of pairs, unable to reproduce annually due to an immense population of rats.
