Description

Bonham's Milestone is a stone milestone located on London Road in Holybourne. It likely dates from the 18th or 19th century and has a shape that resembles a quadrant with a pyramidal top. The milestone is inscribed with the distances to London (45 miles), Alton (2 miles), and Farnham (7 miles). It was moved to its current location when the A31 bypass was constructed.
