Pobull Fhìnn is a stone circle on the Isle of North Uist. The name is Gaelic which can be translated as 'Fionn's people,', 'the white/fair people', or 'Finn's tent'. The stones were probably named after the legendary Gaelic hero Fionn mac Cumhaill.
Of the several stone circles on the island, Pobull Fhìnn is the most conspicuous. It is located on the south side of Ben Langass, and it possibly dates from the second millennium BC. It is technically an oval rather than a circle, measuring about 120 feet from east to west and 93 feet from north to south. Although situated on a natural plateau, the north side of the enclosed area has been excavated to about four feet. At least two dozen stones can be counted, some eight on the northern half and 16 on the southern half, but parts of the circle are devoid of stones. About four feet within the circle at the east side is a tall single stone, and there are two fallen slabs about seven feet beyond the western edge.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.
