6 miles north-west of Spilsby and 7 miles east-north-east of Horncastle, Somersby is both a village and a small parish in the Wold hills. Tetford parish and Salmonby parish lie to the north and Bag Enderby parish to the south. The parish covers about 600 acres (in 1881 and 1900).
The village is just a short walk southeast from Tetford. If you are planning a visit:
Stop and see Somersby Quarry - This small outcrop of Spilsby Sandstone shows perfectly the softness of this stone and its khaki-green colour when exposed to weathering. Although this quarry is now disused, stone has been used to repair nearby Somersby Church.
