Gleaston Castle is a 14th century ruin and is situated in a valley less than 1km from the village of Gleaston.

Its history began back in the 13th century, as construction of the first features of the castle may have have started in around 1297. 

Today the castle is largely a ruin, however key architectural features in the south-east and south-west towers such as staircases, doorways, windows and fireplaces can give clues as to where the floors of the original building(s) once were.

The north-west tower is mostly gone, but it is believed that part of the tower's great hall and passage to its first floor are quite distinct.

The owners of the land have been advised not to allow people to enter the grounds of the castle for safety reasons. However, the ruins can be seen from the road running between Gleaston and the nearby village of Scales.
