The Haltwhistle Burn is a river which lies to the east of the Northumbrian town of Haltwhistle. Rising in the peaty uplands below the ridge of the Whin Sill, the burn passes through the Roman Military Zone south of Hadrian's Wall and through a dramatic sandstone gorge before descending between wooded banks to the South Tyne Valley. The Haltwhistle Burn drains an area of approximately 42 km2. Today, the Burn is a haven for wildlife and a popular walk for residents and tourists but from Roman times until the 1930s the combination of valuable minerals and water power attracted a succession of industries which provided goods and employment to the town.

Unthank Hall is a Grade II listed property now serving as commercial offices, situated on the southern bank of the River South Tyne east of Plenmeller, near Haltwhistle, Northumberland. In the 16th century the manor was owned by the Ridley family and it is possible that the bishop and martyr Nicholas Ridley was born there. The house, which was built in the 16th century, incorporating an ancient pele tower, was substantially remodelled and extended in 1815. The Hall came into the ownership of the Dixon family of Belford Hall, and then by marriage to the Browns. Dixon Brown (1776–1852) changed his name in 1825 to Dixon Dixon. The house was substantially remodelled in 1815. His nephew Rev Dixon Dixon Brown [JP, DL, MA] (1826-1901) rebuilt the Hall between 1862 and 1865, in a neo-Tudor style, both times by Newcastle architect John Dobson. Dixon Dixon Brown was educated at Rugby and Exeter College, Oxford. He sold Unthank Hall in 1897. Much of the 1865 house was demolished by further alterations in 1900, and a significant reduction in size was made in 1965.
