Wilmington Priory: The Long Man’s Medieval Neighbour

A priory from another country

Wilmington Priory was what medieval England called an “alien priory” — a religious house run on English soil but owned by a monastery abroad. In this case the parent was the Benedictine Abbey of Notre-Dame de Grestain, near the mouth of the Seine in Normandy. A small monastic cell existed at Wilmington by the time of the Domesday survey in 1086, and it was enlarged into a priory around 1243. But it was never a grand affair of cloisters and chapter houses: at most it housed a prior and perhaps two or three monks, and its real job was practical — acting as the estate office from which Grestain Abbey managed its scattered English lands. Being handy for the crossing to Normandy, Wilmington was Grestain’s English headquarters.

That foreign ownership eventually doomed it. During the long medieval wars with France, alien priories were viewed with deep suspicion as potential nests of enemy spies, and in 1414 King Henry V suppressed them all. Wilmington’s lands were handed to the Dean and Chapter of Chichester Cathedral, and its life as a monastery came to an end.

The Conqueror connection

Here is what gives little Wilmington its touch of greatness. The mother house at Grestain had been founded by Herluin de Conteville and his wife — and that wife was Herleva (also called Arlette), the mother of William the Conqueror. Herluin was William’s stepfather. The priory at Wilmington, as a cell of Grestain, thus carried the considerable prestige of a direct link to the family of the man who conquered England in 1066. There’s a later royal footnote, too: tradition records that Eleanor, daughter of King John and wife of Simon de Montfort, stayed at Wilmington on the night before the Battle of Evesham in 1265 — the battle in which her husband was killed.

Did you know? The priory sits directly below the Long Man of Wilmington, and the two share an owner and a rescuer: in 1925 the Duke of Devonshire gave both the priory and the giant hill figure to the Sussex Archaeological Society, which cares for them to this day.

Four hundred years, never sold

After the Reformation the priory became a private manor house, and then followed one of the most remarkable ownership stories in Sussex. Granted in 1565 to Sir Richard Sackville, the house was never once sold for the next 360 years — it passed purely by inheritance and marriage, from the Sackvilles to the Compton family (later Earls of Wilmington) and then to the Cavendishes, the Dukes of Devonshire. That’s the same Compton line that gave Eastbourne Compton Place and a Prime Minister, and the same Devonshire family that built the modern resort. The surviving building is an atmospheric, L-shaped medieval house — much of it 14th-century, given a comfortable Georgian makeover in the 1700s — with a beautiful vaulted stone entrance porch, a mullioned window in the ruined Great Chamber, and a medieval vaulted undercroft among its treasures.

The church and the ancient yew

Because the monks had no monastic chapel of their own, they worshipped in the parish church next door, the Church of St Mary and St Peter — an 11th-century building, also Grade I listed, that still stands beside the priory. Its greatest wonder is in the churchyard: an enormous yew tree estimated at around 1,600 years old, with a girth of some 23 feet. This astonishing tree was already ancient when the Normans arrived; it was a sapling, perhaps, in Roman Britain. Standing beneath it, looking up at the Long Man on the hill above, you feel the sheer depth of time layered into this one quiet corner of Sussex.

Visiting Wilmington Priory

Wilmington village sits just off the A27, roughly six miles from Eastbourne, and makes a lovely stop on any trip to the Long Man. The priory itself is now leased to the Landmark Trust — the building conservation charity — and beautifully restored as self-catering holiday accommodation, so it isn’t a ticketed visitor attraction you can tour at will. But you can admire the priory’s medieval frontage and ruins from the neighbouring churchyard, visit the ancient church, and stand beneath that extraordinary yew, all for free. And of course you can climb straight up to the Long Man from the village. For those who’d like to go further, staying overnight in the priory itself is possible through the Landmark Trust.

Good to know: The Landmark Trust occasionally opens its properties to the public on special open days. As access to the priory interior is otherwise limited to those staying there, it’s worth checking the Landmark Trust website if you’d love to see inside.
