There are three so-called passage graves lying only a couple of hundred meters from the hamlet Mysinge. A passage grave is a grave that is built of enormous stone blocks and surrounded by a cairn. The passage graves in Mysinge lie on the land ridge with openings facing southwest. The grave that has been described here has been excavated several times. It has been established that at least 30-40 persons were buried in the tomb, possibly as many as 70 persons.
Within the tomb there were remains from the greater part of the late Stone Age. It was found that the tomb was used in three different periods, the latest of which being the early Bronze Age. The oldest burial to have taken place is thought to have been in circa 3500 B.C., which makes the tomb the oldest passage grave to have been found in Scandinavia. The other two passage graves have not been excavated, but it would not be surprising if they were from the same period. The passage has 5 stones on each side and opens up to a chamber of 9 stone blocks. The roof of the chamber is made of 3 larger stone blocks with the flat side of the stones always turned inward toward the tomb.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
