The remains of a lock can be recognized on the Prinsengracht side.

That lock was necessary because the water of the Prinsengracht (along with the rest of the Jordaan Canals) remained at the polder level, while the water level in the Leliegracht, Keizersgracht and Herengracht was at the higher city level.

Six of the eleven Jordanian canals were filled in in the 19th century.

Only the Bloemgracht, Egelantiersgracht, Lauriergracht, Looiersgracht and Passeerdersgracht remained besides the canal belt Prinsengracht, Keizersgracht, Herengracht, Singel, Lijnbaansgracht, Brouwersgracht, Leliegracht and Leidsegracht.
