Maybe, but 3 sets of gate recesses.
Not much on Canmore about it.
A search shows that a photo of the lock from the dig in 1994 is in the Callender collection.
From Secret Scotland.
Carron Canal
The canal ran east from the Carron Ironworks parallel to the River Carron for a distance of about half a mile where it joined the river through a lock. This was at the highest navigable point on the river at the time. About halfway along the canal a small spur ran north west to a brickworks.
RCAHMS dates the construction at 1781. This came from an inscription uncovered during an archaeological dig in the 1990s prior to a housing development on the site. It is believed that this construction re-used stone from a nearby beehive-shaped Roman monument called 'Arthur's O'On' (Arthur's Oven), thereby destroying it. Drawings of this structure, believed to be a victory monument, appeared in the 1743 book "The Lands and Lairds of Dunipace". The date of the canal's abandonment is not known at this time but both are on maps dating to 1864.
