The Old Mill House, with wheel, today
The Braid Burn, which flows through the area, provided the natural power for a mill, which existed in the time of David I.
In 1143, a charter given to the monks building the newly established Holyrood Abbey granted them the rights over the mills at Libbertun, giving an early record of this activity in the neighbourhood.Then, in 1329, King Robert the Bruce made a grant to the Abbey of the Blackfriars of 'six merks from the mill of Nether Liberton', giving further evidence of this important trade in the village. 
The line of the mill lade, the stream dug to feed the mill, can still be seen starting in Double Hedges Park, behind the petrol station, and striking away towards Nether Liberton village. The name Liberton Dams given to the area around the crossroads at the foot of Liberton and Kirk Braes comes directly from the fact that the Braid Burn was blocked near this point to power a waulk mill and a textile mill, after which the stream culminated in a millpond just behind the doocot on Gilmerton Road. From here the lade ran under the Gilmerton Road, and the grounds of Nether Liberton House, to feed the corn-mill and then drain back into the burn further on.
The last recorded miller working at Nether Liberton was Andrew Dick, who ceased his trade around 1840, though, as a memento of the building's former life, the old mill-wheel can still be seen on the gable of the Mill House from the Braid Burn Walk between Gilmerton Road and Cameron Toll Centre.
