The paintings date from the early 12th century. They survived due to being covered by plaster until uncovered in 1866.[4]
The painters used colours made from locally available materials — red and yellow ochre, lime white, carbon black, and a green from copper carbonate.
The paintings are in two tiers on each wall and originally had inscriptions describing the scenes above them. One of these can still be seen on the east wall of the nave.[5]
On higher ground on the south side of the village are the remains of Hardham Priory, the Priory of St Cross, which was an Augustinian monastery established in the middle of the 13th century.[6]
In the late 18th century a canal tunnel was built on the Arun Navigation to avoid a large loop of the River Arun.[7] The railway line from Pulborough to Midhurst passed over the tunnel, and when the canal closed the railway company broke into the tunnel and filled that part of it under the rails with chalk. On 18 October 2019 the tunnel was Grade II listed.
On 1 April 1933 the parish was abolished and merged with Coldwaltham.[8]
