Harewood Estate is surrounded by old mine workings, so the house faces towards Morwellham Quay.

The Saxon manor (held by Asgar) was taken over, and in the 14th century became part of the Duchy of Cornwall: one of the 17 Antiqua maneria.

[1] During the civil war, the house was commandeered by the cavalier army fighting the roundheads in Devon.

A granite cross at the eastern end of the churchyard marks the grave of Sir William Lewis Salusbury-Trelawny, 8th Baronet, of Harewood House, Calstock, part of Salusbury-Trelawny baronets, who was for some time the Lord Lieutenant of Cornwall and M.P.

Whilst West Harewood House is a single residential property the East comprises two.
