“Until now the Mayburgh henge has been considered exceptional in that it lacked a ditch and its single bank was composed of small river derived stones. The Catterick henge appears, from the excavated evidence, to be of similar plan and construction, and it is only slightly larger than Mayburgh, which has diameters of c. 87.5m (internal) and c 124m (external) with a single entrance through the 36.6m wide bank. Unfortunately none of the apparent gaps in the bank at Catterick can be positively identified as entrances”. P. R. Wilson – Catteractonium.
