Among the many locks in the harbor of le Havre, this one opens on the Bassin de l'Eure, then the Canal of Tancarville, an essential waterway used by huge cargo boats coming to be unloaded. The dominating office on the left would be a dream place to an artist's workshop. But it probably sees more ships than any one can imagine, although it looks so quiet. And this a constant thing in the big harbor city. The pace is rather slow, hiding an enormous activity. The ships, given their size, cannot be fast and give the visual rhythm to the landscape. Far away in the sea, you can usually observe a large quantity of boats waiting their turn to enter the harbor. The other element of rhythm is of course the tide. So, even though everything seems smooth and quiet in le Havre, you have these gigantic container ships often carrying 17 000 containers on board slowly passing through and it is disturbing to imagine such turnover when you have this impression of lazy pace watching the boat traffic.
