Just to the south of Promenade Classique is the Alexandria Canal Tide Lock. This was one end of a seven mile canal that connected Alexandria to the much more famous and successful C&O Canal in Georgetown. This canal was built in 1843 and remained in operation until 1886. It included four locks to raise and lower ships 38 feet for this short journey. This small park holds the last remaining lock from this long forgotten transportation channel.
These parks are at the base of First Street along the Potomac River, a mile north of King Street.
