Monastery of San Salvador de Villanueva was founded in the 10th century by Count Santo (Osorio Gutiérrez). This Benedictine monastery today houses the Museum of Religious Art. The whole complex has been declared a Property of Cultural Interest, and consists of an abbey and the church, as well as various chapels, a monastery, two cloisters and a courtyard. The church’s Baroque façade is particularly worth noting. It was renovated in 1732 by Casas y Novoa, the master architect behind the cathedral in Santiago de Compostela.
La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group.
