Tunnel ventilation
Jan. 16th, 2016 12:45 pmThese are the ventilation towers for the Velsertunnel. The photo was taken from top of a cruise ship passing through the IJ (under which the tunnel runs). Aside from the aesthetics of the towers (and they have been declared a national monument), the two people sitting in lawn chairs at their feet watching the ships go by on a summer's day truly make the picture for me.
