[2] Barnack is in the north-west of the unitary authority, 4 miles (6.4 km) south-east of Stamford, Lincolnshire.

From 1894 until 1965 there was a Barnack Rural District that was a subdivision of the Soke, and which formed part of Huntingdon and Peterborough until 1974.

[3] Barnack is notable for its former limestone industry, its Anglo-Saxon parish church and an unusual early Bronze Age burial.

There is a large "beaker" pot and a copper dagger, common items found in graves of the time.

There is also a piece of oak charcoal; it is unknown what this was for and archaeologists have been unable to provide an adequate explanation why it was buried in the grave.

There is an unusual pendant made of either bone from a sperm whale or walrus ivory, but the most luxurious item is a stone wrist-guard.

The wrist-guard, made of greenstone, was never intended to be worn since the gold caps in the holes would have stopped it from being tied to the arm.

Fewer than a hundred such wrist-guards have been found in Great Britain, and the example from Barnack is arguably the finest.

[6] The interior of the church includes a high-quality late Anglo-Saxon Romanesque sculpture of Christ in Majesty.

[6] Oolitic Lincolnshire limestone, including some called "Barnack rag", was a valuable building stone first used by the Romans.

Quarrying continued in the Middle Ages when the abbeys at Peterborough, Crowland, Ramsey, Sawtry and Bury St Edmunds all used Barnack stone, and the monasteries frequently were in dispute over the rights to it.

The Syston – Peterborough line was absorbed by the Midland Railway, which in 1858 renamed the station Uffington and Barnack.

The London and North Eastern Railway absorbed the GNR in 1923 and closed the branch line in 1929.

The painter Wilfrid Wood (1888–1976) lived in a 17th-century thatched cottage, Littlefield on Station Road, Barnack from 1938.

[20] Barnack has a primary school, a pub,[22] two bed and breakfasts, a MOT test centre and a garage.
