Greys Court, a Tudor country house with medieval origins dating to the 11th century, sits nestled in the Chiltern Hills surrounded by peaceful gardens and ancient parkland. The Great Tower, built around 1347, stands as the last remnant of the medieval castle, overlooking walled gardens that span 900 years of horticultural history. The house features rare Tudor elements including a working donkey wheel well, fine 18th-century plasterwork, and 16th-17th century Swiss stained glass. The series of intimate walled gardens include roses, wisteria, an ornamental kitchen garden, and a modern maze, all set within 75 hectares of Chilterns countryside with waymarked walks through beech woods. **Filming Scenes:** Greys Court appeared as 'Eryholme,' the modest property the Crawley family considered moving to during their financial crisis in Series 3, which they planned to rename 'Downton Place.' The pivotal scene featured a family picnic on the lawn in front of the house, where they discussed downsizing from their grand estate. Set in May 1920, this emotional sequence showed the family confronting potential loss of their ancestral home due to Lord Grantham's failed investments. The Tudor house's more modest scale compared to Highclere perfectly illustrated the dramatic reduction in circumstances the family faced, making their eventual salvation all the more poignant.
