Os grid reference NY.071 254. St Oswald's church stands at the western edge of the village of Dean beside the road to Branthwaite. The village is located some 5 miles due south-west of Cockermouth and about 6 miles to the south-east of Workington.
In the nave of St Oswald's church there is now housed a small sandstone boulder that has a well-defined central cup-mark around which are two large concentric rings, a third ring being left open - perhaps indicating a portal (gateway), and three other well defined cup-marks at the side of that, one of which has become almost adjoined to the other through erosion.
The boulder was ploughed up in a field at nearby Park Hill to the south-west of the village in 1918. It was then placed in the churchyard but, in recent times it was brought into the church for safety reasons.
