One of a number of prehistoric hut circles recorded on Mull Hill, below the stone circle. This hut circle is identified as Hut B (by Kermode & Herdman, 1914). The northeast half of the circle was described, with the majority of its stones prostrate. The largest erect stone is 0.5 metres high, 0.5 metres wide and 0.2 metres thick. It has a diameter of 4.0 metres and the thickness of the wall is 1.2 metres. 


The circular foundations of 3 or 4 other huts measuring between 2.8 metres to 4.2 metres ( 8-12 feet) in diameter were seen, further to the east of the 'Lag-ny-Boirey' settlement.
