Berth-ddu barn

Berth-ddu barn is a 16th to 17th century outfield barn and cowhouse featuring 3 1/2 bays and a lean-to at the southeast end. It is constructed on timber crucks, clad with weatherboarding, and topped with a corrugated iron roof.

The barn retains four cruck frames that span approximately 4 meters and extend to ground level. The half bay at the end is likely a result of the northwest end bay being cut back and replaced with a roughly formed timber truss. Most of the cruck blades are intact down to the ground, although the end couple seems to be founded on a cross sill, with less evidence available for the others. All crucks appear to be closed trusses, featuring tie and collar beams, cross rails, and raking struts to the blades. Many panels were originally infilled with wattle and daub, particularly in their upper sections. The crucks have a yoke apex and ridge (Alcock Type L1) and are trenched for three tiers of purlins. The outer walls consist of two panels high, with square framing that was also originally filled with wattle and daub. One blade has been lost below tie level.
