This huge timber-framed barn was built by the Order of the Knights Templar at Cressing some fifty years before the more refined Wheat Barn whose west end it faces across the farmyard green. Constructed in oak in the Romanesque tradition of carpentry of the early 13th century, it was built of 480 oak trees felled between 1205 and 1235, barely 100 years after the granting of the site to the Order by Queen Matilda.

This wonderful building was constructed about 50 years after its neighbour, the Barley Barn. The constructional details of both barns were important in the development of the technique of dating timber-framed buildings by the types of carpentry joints used. This technique was pioneered by the late Cecil Hewett. (info taken from the official site)
