[Area NY 843653] The medieval village of Haydon was moved from near the old church in the 16th century. The prior of Hexham also held a tithe barn here. (1)(2)

There are no visible remains of the village or barn, and no indications on available aerial photographs (RAF 1946). (3)

The manor of Haydon was in the lordship of Langley. In 1365 Haydon comprised 16 husbandlands, 11 cottages and three 'free' husbandlands. In 1471-2 the bailiff's accounts listed only nine husbandlands and eight cottage holdings, a ninth cottage being waste. The survey of 1569 listed six tenements, and the same number appeared in the survey of 1608. The Hearth Tax of 1666 listed 31 houses in the township. Many were probably in neighbouring hamlets. A rental of 1669 recorded six leasehold tenants at Haydon Town, by 1735 the number had halved. In 1797 the freehold was obtained by Greenwich Hospital and field boundaries were adjusted and new farm buildings erected. It now comprises two farmsteads.
The present road between the two farmsteads runs through the site of the village green. A few insubstantial earthworks are visible in a close on the south side of the road.
An IPM of 1499 recorded an ancient manor at Haydon, then lying waste. Its site is unknown. (4)
