Mont-Terri Castle is a ruined medieval castle above a prehistoric hillfort on Mont Terri, located in the municipality of Cornol.
Mont Terri forms a buttress of the Lomont ridge (part of the Jura mountains), and is separated from it by a saddle called Derrière Mont Terri. The wooded summit forms a plateau four hectares in area. It is bounded on the west and southwest sides by steep cliffs, the remaining sides are protected by an ancient rampart. At the highest point of the plateau are the remains of a medieval fortified tower.
The summit of Mont Terri is known locally as 'Julius Caesar's Camp'; however, the earliest traces of habitation are from the Neolithic era. Pottery finds suggests that there was occupation during the Middle and Late Bronze Age. During the 1st century BC, a rampart was built of typical Gallic construction, a Murus Gallicus; it has been associated with the Gallic Wars, but the only firm dating for the site is a later Roman coin from the reign of Augustus. There are also finds from a further period of occupation in the 4th century AD and other finds extend into the 10th century. A stone tower was built on the site in the 13th century, probably replacing a previous wooden one, and is probably the 'Château Thierry' mentioned in contemporary texts.
The first investigation of the site was by an antiquarian and Jesuit priest, Father Pierre-Joseph Dunod, at the start of the 18th century. Writing in 1716, Father Dunod speculated that the site was the scene of a decisive battle between Caesar and the Suebi tribe led by Ariovistus. There were later excavations by the owners of the site, Koeckler and Maupassant, who were found to have planted antiquities that they had purchased elsewhere, the deception being uncovered in 1862 by archaeologist Auguste Quiquerez (1801-1882). In the 20th century, methodical excavations by Alban Gerster (1898-1986) and in 1984 by a team from the University of Basle, have uncovered a range of finds from Neolithic flint arrow heads to a 10th century dinarius coin from the reign of Louis IV of France.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
