Monument record BNH 053 - Earthworks of post medieval boundary banks

Series of two intersecting field boundary banks on Thetford Heath. One runs in an approximately E-W direction, from TL 8450 8060 to TL 8493 8048 (looks as though it once carried on further to the east); the second bank runs initially north from TL 8476 8030 TO tl 8506 8075, but when it hits (and intersects) the E-W bank, it veers off to the N-E. Near the termination of the latter bank is a curious circular depression with a `ditch' around the SE side (doesn't look like a conventional marl pit; possibly associated with recent military activity). Dimensions of both banks approximately 16-18m wide by 60-80cm high - low and spread. The banks conform to land parcels on the 1840 tithe map; these boundaries are represented by dotted lines on the 2nd edition OS map, suggesting a shifting arable/heath usage. Currently owned and managed by the Norfolk Wildlife Trust in conjunction with English Nature (S1). Management report prepared for NWT by K Sussams in January 1997.

The polygon for these post medieval boundary banks has been amended from aerial photograph evidence (S2). The possible marl pit and/or military training feature dug into one of them has been recorded under BNH 113, but see BNH 051 also for possible confusion with barrow mound.
