An earlier house on the site was one of many places the poet Charles d'Orleans was lodged during a long imprisonment in England after his capture at the Battle of Agincourt. Charles wrote one of my favourite lyrics of any time or any language- "Le temps a laisse son manteau."
The present house dates from the 1660s and tradition says- as it says of many buildings of the period- that Christopher Wren had a hand in the design. Arthur Conan Doyle was a frequent visitor in the days of his fame- when he was living just down the road in Crowborough- and used it- disguised as Birlstone Manor- as the venue for the shotgun killing in The Valley of Fear.
The house is a private residence- and so not open to the public- but the gardens can be visited- at a price- and are very pretty.
Twice a day- every day bar Fridays- Eddie and Veronica Hare of the Groombridge Raptor Centre fly their birds in the grounds. Here's Veronica with Maleficent the African Fish Eagle.
Groombridge Place is really one of the prettiest houses in England; I fell in love with it when it was used in the 2005 "Pride and Prejudice" film. (Especially how the entrance to the portico leads directly into a piece of wall between two windows... Imperfections are endearing in a building, I find - which is just as well, considering the state of my house!)
