The Archaeological Park of Cava d'Ispica is located in the northern part of the valley which is extended among large and impressive gorges for about 14km. The monumental archaeological evidences which are currently visible have been found thanks to the excavations in the rock and they can be ascribed to three periods: the prehistoric period, the Late Antiquity and the Middle Ages.
Evidences of the Ancient Bronze Age (the Castelluccio age which dates back to 2200- 1450 BC) are a number of settlements scattered along the valley, with oven tombs necropolis. Among them, there is the necropolis of Baravitalla, located in the northern part of the quarry, with a monumental well preserved tomb, with a façade decorated with ten pillars. In the above plain, the remains of the village have been found, together with the original archaeological finds (e.g. plates with spheres) and numerous terracotta ornaments.
Even during the Late Antiquity, the valley featured an impressive necropolis with catacombs and small burial tombs. Among them, there is the Larderia catacomb, which is divided into three aisles and contains more than 400 burial graves, dating back to the 4th and 5th century A.D. Other Christian evidences can be found in the other burial area called “Camposanto caves”.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.
