Hackness is mentioned as the site of a double monastery or nunnery by Bede, writing in the early 8th century. The church of Saint Peter, a Grade I listed building, parts of which date from the 11th century, has fragments of a high cross dating from the late 8th or early 9th century.
Hackness Hall and its landscape gardens were created in the 1790s. The house, a Grade I listed building, was commissioned by Sir Richard Van den Bempde-Johnstone, who had inherited the estate through his mother. A new entrance was added in 1810. Fire damage in 1910 was restored under the direction of Walter Brierley.
The parish council is Hackness & Harwood Dale Group Parish Council which covers the six parishes of Broxa-cum-Troutsdale, Darncombe-cum-Langdale End, Hackness, Harwood Dale, Silpho and Suffield-cum-Everley.
There is a tennis club in the village with three grass courts and two tarmac courts, situated on the road to Lowdales and Highdales. The Club recently celebrated 90 years of tennis in Hackness in 2013.
