Block of fields between Thurlstone and Royd Moor Reservoir with s-curve boundaries. Medieval strip layout is fossilised by the present field boundaries giving significant legibility of the open fields. Around 25% of boundaries have been lost since 1851. Possibly enclosed in the late medieval - early post-medieval period. Possibly as part of the agreed enclosure of the west townfield in 1696 (Hey 1979, 73). Folly Lane appears to cut through this pattern of fields from the junction with Norwood Lane up to the crossing over Maze Brook indicating a diversion from the original path layout. The current route of the road is found on OS maps of 1851.
