White Hart Dock on Albert Embankment has been so hidden that many people did not know it existed.
Indeed I confess that I did not ask readers to note the blank high concrete wall when writing the directions between Lambeth and Vauxhall Bridges.
The surprise is that the draw dock opening on to Black Prince Road is on the inside of the embankment main road. Boats and barges must pass under the road.
I have written a description of an event at the dock on the London SE1 website.
