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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
