Chrishall Castle is a ringwork located in Park Wood in the village of Chrishall in the north-west of Essex. It seems likely the castle would have been constructed of wood.
The ringwork is 85m east-west by 90m north-south in diameter and is surrounded by a moat which is mostly dry, though the west side does hold water. The interior of the ringwork is level, though there are denuded ramparts which could have possibly enclosed the whole site.
The site of Chrishall Castle is very overgrown. The castle is on private land and can only be viewed from a footpath which runs alongside the site. The castles lies 70 metres north-east of the village church in Park Wood.
