The Gialia Monastery is a ruined medieval Georgian Orthodox monastery dedicated to the Virgin Mary. Located in a forest some five kilometers from the coast near the small town of Polis Chrysochous, the ruins were identified, in 1981, by the Georgian scholar Wachtang Djobadze of California State University on the basis of the medieval Georgian accounts. It was not, however, until 2006 that a systematic archaeological research followed after the Georgian and Cypriot governments agreed to jointly investigate the ruins.
It was reported in 2008 that excavation evidence indicated the monastery was commissioned in the late 10th century by Georgian King David III Kuropalates and that renovations were made during the reign of David IV Aghmashenebeli (1089-1125). The monastery is certainly attested in the 12th century, when it was renovated at the behest of Queen Tamar of Georgia (1184-1213). Ancient Georgian sources report that it was in Georgian ownership until the 14th century, and graves and other items uncovered indicate that it was in use between the 14th and 16th centuries. It was reportedly plundered and destroyed in the 16th century, but appears to have been in use as recently as 1935, until final destruction by an earthquake in 1953.
Two main structures have been identified: the earlier Virgin church, and the later St. George's church dated probably to the 11th and 12th centuries respectively. Remains of Georgian paintings and inscriptions from the 13th and 14th century have also survived.
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.
