Upminster (Borough of Havering)

NGR:  (To follow)

Set against wall outside 217 Corbets Tey Road.  Only known survivor along a route from Romford to Grays.  This would be the 16 miles from London.  A similar stone, although described as a boundary stone, is on display in the Upminster Tithe Barn Museum.  Its appearance and dimensions, as well as its original location, seem to indicate that it may have been the 13 miles from London stone.
