Camden Lock (via Wikipedia):
The locks were constructed between 1818 and 1820 by James Morgan, with John Nash, supervising engineer. It is the only twin-lock remaining on the Canal, the remainder having been modified to single lock operation. […]
The yard and former warehouses, an area known as Camden Lock, are on the north side of the canal, at the junction with Chalk Farm Road. This area is adjacent to a canal basin and holds Camden Lock Market, one of the group of markets often called collectively Camden Market. It is a busy market popular with visitors, with music venues, cafes and canal towpath walks.
