Just inside the present roofed section of chamber
B.
The approach passage was constructed of dry-stone walling with a corbelled roof,
the chamber had low
orthostatic walls and was roofed with slabs, the only chamber at Belas Knap
known to have this roofing method.
The chamber narrows slightly at its midpoint where a transverse orthostat
projects out into the chamber, this
stone can be seen centre right above.
