Tulach an t'Sionnaich

Tullow to t'Sionnaich (German mountain of the fox ), a periodically extended cairn at the northern end of Loch Calder (lake) in Caithness in Scotland. He was 1961 and 1963 excavated in advance of raising the level of the lake. Prior to the excavation of a 60 m long, twelve feet wide stone pile with scarcely recognizable structures was present. The northwest-southeast -oriented Cairn had in the southeast with the 1.8 m higher and slightly wider end. Late -scale digging average 15 m from the southeast end of the cairn.

The excavation revealed that the monument was initially a square passage tomb in a circular cairn of 10.5 m in diameter. Its 2.1 m long corridor was to the south. The outer gear end was closed by the boundary stone wall that surrounded this cairn.

After a possibly short existence of the first Cairns, which may have already been on a D- or shoulder-like platform, it was built over a heel- shaped cairn, which was identified as the oldest on the Scottish mainland. Its small size makes it within the monument in a class frühtypologische sequence. The new, built over the entrance to the passage tomb facade was not interrupted. However, problems prevented the full recovery of the basic plan. The plant seems to have been about 15 m wide and about as long. The north end is located in the region of the trench, where remains were identified by a dry stone wall.

After some time, the entire structure was built over a Long Cairn, which was surrounded by a low outer wall and its southern end was beyond the old facade. This Long Cairn was about 38 m long and tapered from its 10.2 -m-wide pseudo - facade slightly to 7.8 m wide, weakly convex north end. He lay just east of the axis of the heel- shaped Cairns, probably better to use a natural ridge, and the height, which accounted for except on the south end not more than 0.9 m to enlarge. Selective cuts in the Cairn were box-shaped fixtures, but were part of the Cairn structure.

Few finds were made, but the pottery suggests that the heel- shaped cairn was in use during the period of undecorated Neolithic pottery. He walked upon the arrival of the cup cultures from the use, and the Long Cairn was already established before an urn was deposited outside the enclosure.

The south-west side, including the Chamber of Tullow t -Sion Aich, has been eroded from rising level of Loch Calder, but the main part of the Cairns remained and is covered with grass.
