Barpa Langass is a Neolithic chambered cairn, which now survives as a massive pile of stone. It is located on a hill overlooking a dramatic landscape of barren peatland. The cairn is roughly 16 feet high, and around 82 feet across. The inner chamber is still accessible. From the east side of the tomb the narrow passage leads to a wide chamber. It is difficult to judge the original appearance of the cairn, but it has been suggested that it had a more bun like appearance with outer facing stones and an earthen top portion. This great cairn is the only chambered cairn in the Western Isles with its chamber still roofed over. During excavation in 1911 traces of burnt burials, beaker shards, an arrowhead and a disc of mica (maybe a pendant) were found. On the south side of the same hill is Pobull Fhinn an ancient stone circle.
At the time the cairn was built the Western Isles had a much milder climate, the peat bogs were not yet formed, and the landscape would have been more like southern scrubland and woodland. It would have been capable of providing pasture for grazing animals. Barpa Langass stands on the north side of Beinn Langais, and just half a mile from the stone circle of Pobull Fhinn To find this grand cairn travel to North Uist and it is signposted off the A867 Lochmaddy-Clachan road.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.
