About
Greys Court occupies a site of layered historical complexity in the wooded Chiltern Hills above Henley-on-Thames — a place where the medieval, Tudor, Stuart, and Georgian have accumulated gradually over centuries, each period leaving its contribution to a complex of buildings and gardens whose intimate, human-scaled character is quite unlike the grand country houses that dominate the heritage landscape of the Thames Valley. The medieval tower (a remnant of the fortified manor house of the Knollys family, who held the estate for generations), the 16th-century house rebuilt after the original castle fell into decay, the walled gardens developed across three centuries of cultivation, and the extraordinary donkey wheel house — a working example of the animal-powered well machinery that once lifted water from the chalk aquifer below — together form a property of remarkable diversity within a modest compass.
The Knollys family were significant figures at the Tudor court — Sir Francis Knollys served Queen Elizabeth I as Treasurer of the Household and Vice-Chamberlain, and the family's Catholic connections gave them a complicated relationship with the religious politics of the Reformation. Their presence at Greys Court across the 16th and 17th centuries shaped both the physical character of the house and the human stories embedded in it. The house that survives from this period is domestic in scale — not a grand display of wealth and power but a working gentry house, with rooms that convey the practicalities of household management alongside the aspirations to comfort and status that the Tudor gentry expressed through architecture and furnishing.
The gardens are the property's greatest contemporary asset. The walled gardens — developed in successive periods and now managed with exceptional horticultural skill by the National Trust — include a productive kitchen garden growing fruit and vegetables by traditional methods, an ornamental garden with seasonal planting of real quality, and the famous Archbishop's Maze. Designed in 1981 by Adrian Fisher at the commission of Lady Brunner to mark the enthronement of Archbishop Robert Runcie, the maze is laid in grass in a symbolic pattern evoking the Christian cross — a meditation on faith, decision, and the journey to the centre that has become one of the most visited features of any National Trust garden in southern England.
The donkey wheel house — a rare surviving example of the animal-powered mechanism that raised water from the chalk wells of the Chilterns, preserved with its original wooden wheel and lifting gear — is perhaps the most unexpectedly moving object on the property: a piece of pre-industrial technology that conveys, in its large-scale wooden simplicity, the ingenuity and labour that provided water to households before the era of pumping engines. The donkeys that turned the wheel are long gone, but the machinery that their circular walking powered remains as evidence of a world before fossil fuels.

Highlights
The Archbishop's Maze
Designed in 1981 by maze-maker Adrian Fisher for Lady Brunner of Greys Court, to mark the enthronement of Archbishop Robert Runcie as Archbishop of Canterbury, the Archbishop's Maze is one of the most visited features of any National Trust garden in southern England. Laid out in grass in the walled garden, its symbolic pattern — evoking the Christian cross — conceals a genuine puzzle: visitors enter at the south and must navigate their way to the central stone, making decisions at each junction that may lead them toward the centre or frustratingly away from it.
The maze rewards patience, observation, and a willingness to retrace your steps — qualities not coincidentally associated with spiritual reflection.
The Donkey Wheel House
The donkey wheel house at Greys Court is one of the finest surviving examples of animal-powered well machinery in England — a large wooden wheel, once turned by donkeys walking in a continuous circular path, that raised water from the chalk aquifer far below the Chiltern Hills surface. The mechanism is preserved largely intact: the wheel, the lifting drum, the chain or rope, and the well shaft are all visible and interpretable.
This is pre-industrial technology of simple genius: before electric pumps, providing water to a house on the dry chalk uplands required either carrying water from distant springs or building exactly this kind of animal-powered lifting mechanism.
The Medieval Knollys Tower
The surviving tower from the medieval castle that preceded the current house is the oldest structure on the site and a tangible connection to the 14th-century origins of the Knollys family's occupation of Greys Court. The tower — solid, austere, built of the local flint and stone — stands in the courtyard as a reminder that this modest-seeming property has a history that stretches back to the decades before Agincourt, when the Knollys family were accumulating the land and status that would eventually bring them to the Tudor court.
The tower is explored in the house visit and interpreted in relation to the broader medieval history of the estate.
The Tudor House Interiors
The house rebuilt after the medieval castle fell into decay is a modest but telling example of Tudor gentry architecture — rooms of human scale with furniture, portraits, and domestic objects that convey the life of a Chilterns landowning family in the 16th and 17th centuries. The house lacks the grandeur of the great Tudor palaces or the ambition of the major country houses, but this is precisely its virtue: the domestic scale makes the lives of the Knollys family imaginatively accessible in a way that grander properties resist.
The historic character of the rooms is maintained by the National Trust with a light interpretive touch.
