It appears in Domesday Book as "Alresford – forda Ralph de Limesy Mill".

Built as a crossing over the River Aller (from which the village gets its name), it is thought to be medieval in origin.

[6][7] Allerford New Bridge which carries the A39 road past the village is also a Scheduled Ancient Monument and Grade II* listed building.

[9] The village is also home to Allerford House, childhood home of Admiral John Moresby, who explored the coastline of New Guinea and for whom Port Moresby, the capital city of Papua New Guinea, was named.

Other traditional sights in the village include thatched cottages, a forge and an old-fashioned red telephone box.
