Credenhill village has had military connections since 80 BC, when Iron AgeCelts constructed a hill fort and earthwork defence system commanding the surrounding area. The Romans founded the town of Magnis at what is now Kenchester, which was later abandoned during the withdrawal of Roman armies from Britain. In 428 AD Magnis was destroyed by a fire during raids by the Picts and Scots. The remains of the old fort was occupied by the Saxons in 480 AD. The Saxon chief Creoda occupied the fort in 540 AD, and "Creoda's Hill" gave its name to Credenhill. During the First World War, land in Credenhill was occupied by an army unit to store ammunition. In 1939 the land was requisitioned for defence and became RAF Hereford. The 12th-century church of St Mary is a grade I listed building.

Surrounding area
There is an Iron Age hill fort half a mile north of Credenhill. Archaeological finds are in Hereford Museum. The defences of this very large hill fort follow the 600 ft contour and enclose nearly 50 acres. They comprise an embankment and ditch with a slight counter-scarp bank. There are traces of a quarry ditch inside the main rampart around most of the circuit. Original in-turned entrances are at the centre of the east side and at the south-east corner, each approached by a hollow way cut deeply into the hillside. Trial excavation has shown that the internal quarry-ditch is 5–10 ft deep. Its gradual in-filling was found to include various occupation layers associated with rectangular wooden buildings with four corner posts, measuring about 12 x, which had been rebuilt several times in the same place. There were also storage pits and other remains of occupation including pottery with stamped and incised patterns typical of the WestMidlands Iron Age. Date, c. 400 BC; occupied continuously until about 75 AD. The fort and the surrounding ancient woodland are now part of the Woodland Trust.
Notable residents

Thomas Traherne, the 17th-century English poet and religious writer, was rector of Credenhill for ten years.
