Osmotherley probably means the clearing or 'ley', belonging to a Viking called 'Asmund' or a Saxon called 'Osmund'. In the Domesday Book it was recorded as Asmundrelac and subsequently as Osmundeslay and Osmonderlay. Local legend says that Osmotherley was named after the mother of a villager named Oswald or Osmund, who went out to gather firewood in the winter. When she did not return her son became anxious and went out to look for her. He found her lying in the snow, dead or dying from the cold. Because he was not able to carry her back, he lay down beside her and died himself. It is where Oswald's mother lies, hence Osmotherley.
The village school, Osmotherley Primary School, was founded 1857 and the present building dates from 1878. It is on School Lane and has fewer than 50 pupils. Osmotherley has three public houses within a radius: the Queen Catherine, the Three Tuns and the Golden Lion. The village also has a newsagents, a Top Shop, a Youth Hostel and an antique shop. In 2019, the Osmotherley Fish and Chip was named the best in Northern England at the England Business Awards event. Thompson, the shop that served Osmotherley since 1786, and an Art and Craft Shop have both recently closed. The Barter Table on the village green is a five-legged structure with a stone slabon top which is about high. Goods were exchanged or bartered on the table and it is now a grade II listed structure.
Religion
The Anglican parish church dedicated to St Peter is built on a Saxon site and parts of the building date from the Norman period. Largely rebuilt by architect C. Hodgson Fowler in 1892, it is a grade II* listed building. John Wesley preached at the barter table on the green on several occasions, the first in 1745. In 1754 a Methodist Chapel was erected in Chapel Yard. Osmotherley Friends Meeting House, a traditional stone building, was erected in 1690 or 1723. Meetings are held monthly. It is thought that George Fox may have visited the village in the late-17th century.
Geography
The village is in the North York Moors, one of the largest areas of moorland in Great Britain. Cod Beck Reservoir to the north is named from Cod Beck, a tributary of the River Swale. The beck derives its name from the Celtic word 'Coed', meaning woody. Just before Cod Beck reaches the reservoir is a picturesque location called Sheepwash. Osmotherley is close to the western terminus of the Lyke Wake Walk. The official starting point is at the edge of the moors above the village where there is a stone marker. About 1½ miles from Osmotherley near the A19 is Mount Grace Priory. Its ruins are situated at the foot of a steep wooded hill with a footpath leading into the village. The Carthusian religious house was founded around 1396.
Osmotherley is the setting of some of the final chapters of the novelBrother in the Land by Robert Swindells. In the novel, many towns and cities are hit by individually programmed nuclear missiles, but because of Osmotherley's small size, the village is spared.
