Saranta Kolones ('Forty Columns castle') is a ruined medieval fortress inside the Paphos Archaeological Park. It takes its name from the large number of granite columns that were found on the site and probably once formed part of the ancient agora. The Byzantine castle is believed to have been built at the end of the 7th century AD to protect the port and the city of Nea Pafos from Arab raids. It was later remodeled by the Lusignans in the early 1200s.
The fortress had a three-metre thick wall with four huge corner towers and another four intermediary towers along the joining walls and moat surrounding the castle. Access was across a wooden bridge spanning the moat. The square courtyard measured 35 metres long by 35 metres wide, with a tower at each corner. The main entrance was through a fifth, horseshoe-shaped tower on the east side. Destroyed by an earthquake in 1222, the castle was subsequently abandoned.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.
