Bostadh (Iron Age settlement)

The Bostadh Iron Age settlement is located on the island of Great Bernera in the Outer Hebrides, Scotland.

A series of stone buildings were revealed underneath an eroding sand dune over a stretch of 30 metres.

The buildings are bordered by exposed rock to the north, a stream estuary to the south, and Bosta Cemetery in the east.

Finds include a significant number of pottery sherds including 160 rims and 50 bases, Beaker pottery, fish and animal bones (some of which displaying signs of butchering), antler, shells, worked bone tools, fragments of up to three combs, and a lead weight.

[1] Excavations were carried out by CFA Archaeology with the University of Edinburgh with the assistance of students and local community volunteers.

The central hearths in Houses 1-3 are constructed using stones and take the form of a three-sided, open ended rectangle.

An example of decorated pottery that has been tentatively dated to some time from the third to fifth centuries CE was found in House 5.

The presence of a steatite bowl fragment with rivet holes in the midden suggests that the rectangular structure dates to the Norse period.

House 3 was completely dismantled, and its footprint was demarcated with stones and the void that it previously occupied was backfilled.

[1] In 1998 archeological evaluations was undertaken to identify a location near the Bosta Beach settlement that was of a suitable size and free from archaeological remains to construct a replica of one of the excavated Iron Age houses.

The geophysical survey utilized resistivity, electromagnetic, and ground penetrating radar was undertaken to investigate the subsurface in two areas.

[2] At one point the reconstructed house's roof was thatched and secured with a series of ropes and stone weights.

The system of ropes and stone weights is no longer used, but the wooden "horns" at either end of the houses ridge are still present.
