The monument consists of a series of fourteen locks, dating to the 18th century. A lock is a section of a water channel on a canal or river shut off above and below by lock gates provided with sluices to let the water out and in, and thus raise or lower boats from one level to another. The canal, constructed between 1792 and 1798, was connected by tramroad with Blaenavon ironworks and served to bring its products to the docks at Newport. The staircase" of locks is on the Crumlin branch of the Monmouthshire and Brecon canal
