Two kilometers north of Laudun-l'Ardoise, Camp de César is an 18-hectare archaeological site among the most important in the region. On a limestone terrace located 200 meters above the Rhone valley the Gallo-Roman Oppidum presents vestiges of five successive periods of occupation from the Iron Age to the Middle Ages. Located in a belvedere, it offers a remarkable point of view. Many remains have been uncovered during the excavations: forum, basilica, ramparts, craft and housing quarter, necropolises.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
