19th century milestone at Spalding Road, to the south-west of Sutterton. It is of carved stone, and is inscribed 'LONDON 100 MILES, SUTTERTON'. {1} The milestone is depicted in this location on the 2nd edition 25" Ordnance Survey County Series map. The depiction shows the milestone giving the distance to Boston as 7 miles, and to Spalding as 9 miles. {2} No trace of the milestone was found in early 2020, during inspection visits conducted as part of a condition survey of historic milestones in Boston Borough. The stone is thought to still be extant, though lost within extensive scrub and hedging that has grown in this area. {3}
