The High Road is the A1000, formerly known as the Great North Road, parts of it still bear this name.[citation needed] Until the late 19th century its tiny developed area was one of two main settlements in the ancient parish of Friern Barnet, the other being Colney Hatch. It was thus the northernmost settlement in the Ossulstone hundred. Whetstone is also the northernmost part of the parish of Finchley.
