St Stephen's Church, or the Cathedral of the Dales, as it is often called, is the second largest parish church in Cumbria. It is thought to date to about 900-950 AD, a period relating to rule by the Anglo Saxons. It was rebult in 1170 by the Normans, and replaced again in 1240 by the current building and restored in the 19th century. St Stephen's church is a grade II listed building.

The West Tower was erected circa 1506, during more affluent times. At the same time the large arch connecting the West Tower to the Nave was constructed. The West Tower houses a ring of 8 bells.

During the 17th century St Stephen's church fell into disrepair. In 1847 a cardinal program of restoration began, which involved the reconstruction of the chancel and two side chapels. The height of the roof to the nave was increased and a clerestory was added.

The Loki Stone is a 10th century Anglo-Danish cross shaft carved into the bearded figure of a shackled devil, the old Norse god Loki. This is one of the earliest Christian symbols of the devil in human form and is the only example in Great Britain.

The Loki Stone dates to about ad 900-950. It is on view within the church, facing the entrance door.

A capital is the crowning member of a column or the likes, that provides support for a horizontal fixture. Many of the original capitals dating back to the Norman age are on display within St Stephen's Church. They include etched images of strange mannikins and curious flower patterns.
