You would be forgiven for thinking that this was a private house, because nowadays it is precisely that. Built in 1590-ish, it is the original stable block for Chawton house, and typical, if rather grand, of stables built before the Ag Rev. The basic design was the same for a house, barn or almost any other farm building. The horses would be walked in through the front door, probably tethered in pairs along the wall, with a wooden partition to stop them kicking each other, wooden or metal mangers on the walls, and a drain in the centre of the floor. One wing was probably a tack room ; the second storey would be for the storage of hay and feed, and probably provided sleeping for the stable staff.
I imagine that the farm horses would share the place with the riding horses; that was the usual arrangement.
