Pillow mounds

Mediaeval Rabbit Warren, Hollybush Hill - geograph

The most characteristic structure of the "cony-garth" ("rabbit-yard") is the pillow mound. These were "pillow-like", oblong mounds with flat tops, frequently described as being "cigar-shaped", and sometimes arranged like the letter ⟨E⟩ or into more extensive, interconnected rows. Often these were provided with pre-built, stone-lined tunnels. The preferred orientation was on a gentle slope, with the arms extending downhill, to facilitate drainage. The soil needed to be soft, to accommodate further burrowing. This type of architecture and animal husbandry has become obsolete, but numerous pillow mounds are still to be found in

Further evolution of the term

Ultimately, the term "warren" was generalized to include wild burrows. According to the 1911 ''Encyclopædia Britannica'':

The word thus became used of a piece of ground preserved for these beasts of warren. It is now applied loosely to any piece of ground, whether preserved or not, where rabbits breed. see also

The use is further extended to any system of burrows, e.g., "
