This historic lock, officially the Oldbridge Sealock but locally known as Tiernan’s Lock, marks the beginning of the canal section of the Boyne Navigation. It is the only lock on the route that is directly influenced by the river's tide. The robust limestone walls and the associated lock keeper's cottage form a beautiful ensemble of 18th-century hydraulic engineering. For cyclists, this is an iconic point on the Greenway: here you exchange the view of the wide river for the tranquil, green setting of the towpath. An atmospheric place where the history of inland navigation is still tangible.
