Corseul was called Fanum Martis ('Temple of Mars') in Latin and was the capital of the Gallo-Roman province of Coriosolites. It was founded in 10 BC. In the 3rd and 4th centuries, like many other cities, Fanum Martis was renamed for its people, the Curiosolitae. This name change occurred as the Roman Empire weakened and paralleled a revival of the ancient Gallic gods in local religious sculptures and dedicatory inscriptions.
Monterfil, today in Corseul city centre, was the antic city’s trading area and was built on a Roman grid plan. It was laid out around a 10m wide central street and two main perpendicular lanes delineating the blocks or insulae. It was developed in the 1st century BC and remained active until the 3rd century AD when it was burnt. The site has been transformed into an elegant public garden known as Jardin des Antiques.References:
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.
