The Pont de Pierre, meaning 'Stone Bridge', is a Roman segmental arch bridge in Aosta. The bridge crossed the Buthier about 600 m from the eastern exit of the Roman colony Augusta Praetoria; in later times the torrente changed its course, leaving the ancient bridge today without water.
The structure is dated to the second half of the reign of Augustus (30 BC–14 AD), who had earlier founded the military colony Augusta Praetoria at an important road junction (24 BC).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.
