 The tegulation has led many to argue that hogbacks are meant to emulate a house-shape, specifically Scandinavian long houses.Five hogbacks are housed at Govan Old, the largest collection of hogbacks in Scotland; four of these are the largest known hogbacks in all of Great Britain.The smallest of the hogbacks (SM 2, ECMS 2, Lang 1) is the best preserved and exhibits the most decoration; it has been suggested that this style has similarities to sculpture in Cumbria .
