A group of coke ovens can be seen between the main road and Stanley Wood at this site. Some of the ovens are still in quite good condition. They are arranged into at least three lines. They are of 19th century date and are Scheduled Ancient Monuments.

The ruins, earthworks and buried remains of a late 19th century coke works situated in the upper reaches of the Deerness Valley, 150 metres south east of Hedleyhill Colliery village. It was once part of the Hedleyhill Colliery which is now largely cleared and landscaped. The colliery and coke works were in operation from at least 1897 under the ownership of the Weardale Iron and Coal Company. Almost all of the colliery's production, at least in the early years, was transported direct to the coke works. By the mid-20th century the colliery had become uneconomic and was finally abandoned in 1950. The monument includes the best-preserved remains of the Hedleyhill coke works, including the remains of two ranges of coke ovens, one double and one single, of the beehive design developed in, and once typical of, the Durham coalfield. The ovens consist of brick built domes, typically 3.58 metres in diameter, insulated by an earthen bank. A number of the ovens survive to original height and a little over half the circumference remains in most complete examples. The remains of an additional double range located to the west are now very fragmentary and difficult to interpret. Scheduled.
