Set on a hilltop surrounded by vineyards and cypresses, the Gallo-Roman villa of Séviac was a luxurious residence, spread over almost 6500m2. It is today one of the largest Gallo-Roman villas known in the south-west of France. The villa was built in the 2nd century AD and reconstructed in the 3rd and 4th centuries. Later in the 8th and 9th centuries the place was used for a church, burials and necropolis. The villa is distinguished by its exceptional set of Roman age mosaics (over 625m2) and vast baths.
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. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
