Aswardhurn Wapentake was an administrative area - the Danelaw equivalent of an Anglo-Saxon Hundred. The word derived from an assembly or meeting place, usually at a cross-roads or near a river, where literally one's presence or a vote was taken by a show of weapons.
The Aswardhurn wapentake was trianguler, measuring 10 to 12 miles on each of its three sides, bounded by Flaxwell,Kirton and Aveland wapentakes. It is an undulating district, watered by many small rivulets, except the eastern part, which was a low but fertile fen, traversed by the Romas Car-Dyke, one of the most ancient navigable drains in the kingdom. This fen adjoins Holland Fen, from which it is seperated by the Holland Dyke and other drains. Aswardhurn is in the Parts of Kesteven, Archdeanery of Lincoln and Deaneries of New Sleaford and Aveland. There were 24 parishes in the Wapentake.
