The other subgroup is the Borgund group. In these churches the posts are connected halfway up with one or two horizontal double ″pincer beams″ with semicircular indentations, clasping the row of posts from both sides. Cross-braces are inserted between the posts and the upper and lower pincer beams (or above the single pincer beam), forming a very rigid interconnection, and resembling the triforium of stone basilicas. This design made it possible to omit the freestanding lower part of intermediate posts. In some churches in Valdres, only the four corner posts remain (see the image of Lomen Stave Church).
