Shopping centre built by 1983 mapping. This polygon represents the outline of May Day Green as it was in 1777. Barnsley did not move to its current position until the 13th century (Elliot 2002, 27) when the land would have been set aside as common. Prior to this the land was probably unenclosed, possibly used as more distant grazing from the hamlet at Old Town. In the 19th century as the town expanded this area gradually filled, probably with commercial properties. These have been overwritten by the modern development. There is fragmentary legibility of the common as Cheapside follows the edge of the common.
