This probable henge monument, the first identified in Lincolnshire has been identified by crop marks. In measures approx. 20m in diameter, has two entrances (type II) which are aligned on a north west – south east axis. The outer mound was surrounded with at least 24 pits which were equally placed around its circumference, these probably held posts. The henge is not truely circular and is ovoid with it’s longest diameter being in line with the entrance axis.
It has been likened to the Millfield North henge in Northumberland.
