The land and mills of Bonnytoun formed part of the Barony of Broughton mentioned in King David I’s confirmation charter to the Abbey of Holyrood in 1143. Like the nearby village of Canonmills, Bonnington was a milling village making use of the river’s water-power.
The village suffered in 1544 when the Earl of Hertford’s army passed through on its way to attack Edinburgh and again in 1547 after the Scottish defeat in the Battle of Pinkie, both events in the period of conflict known as the Rough Wooing.
In 1617 the land and mills were sold to the Town Council of Edinburgh by the then landowners, the Logans of Restalrig. At the Council’s invitation, a Dutchman Jeromias van der Heill was installed in 1621 as a dyer to teach his craft locally.
The house built for him, named Bonnyhaugh by a later occupant, still stands. When the mill buildings were demolished in the face of local protests in the 1980s, the house was saved, restored and converted into private apartments. The low cottage at its side was the original dying room and later became a blacksmith’s smiddy.
A waterwheel of the ‘undershot’ type, from the Bonnington Mills, has been saved and in the 1980s was moved to a new position on the site of the mill lade. The water level in the lade was controlled by a sluice gate at the nearby weir at Redbraes. The water power generated was used to mill grain, weave cloth, tan leather and manufacture paper.
