Kynnersley Arms Public House Incorporating Remains of Mill and Furnace

The Kynnersley Arms Public House, which incorporates the remains of a mill and furnace, is a public house dating from the late 19th century. It is constructed of purplish brown brick and features slate hipped roofs with tall stacks on the roof slope and sides. The building is two storeys high and has a three-window front, with a prominent canted bay window in the center of the ground floor and an entrance to the left. There is a two-bay range set back to the left.

The main interest of the building lies in the early 19th-century mill located at the rear, which is made of red brick and has a plain tile roof. Notably, there is a cast-iron undershot wheel from a former iron furnace located below the wide round arch to the left. This wheel is now connected to the gearing of the mill but was originally used to activate the bellows of the iron furnace, which is believed to have closed in the 1760s.

Inside the public house, the massive crown and pinion oak gearing of the corn mill is visible through a glass inspection chamber in a back room. This gearing turned the twin millstones, which received grain from an upper floor. A charcoal-fuelled blast furnace was established in Leighton in 1662 and is mentioned again in 1685 and 1698. Additionally, there are historical references to gunshot being stored here for the Royalist forces during the Civil War, after which the furnace at Leighton was 'slighted' by General Waller.
