A place privileged, by prescription or grant the king, for keeping certain animals (as hares, conies, partridges, pheasants, etc.) called beasts and fowls of warren.
A privilege which one has in his lands, by royal grant or prescription, of hunting and taking wild beasts and birds of warren, to the exclusion of any other person not entering by his permission.
Free warren—often simply warren—refers to a type of franchise or privilege conveyed by a sovereign in England to a subject, promising to hold them harmless for killing game of certain species within a stipulated area, usually a woods or small forest. The sovereign involved might be either the monarch or a marcher lord.
