Boterdorpse Verlaat

The Boterdorpse Verlaat is a historic lock in Rotterdam that connects the Rotte River with the Strekvaart in the Bergse Plassen. The waterway was originally used to transport malt waste from the distilleries and breweries in Schiedam and Rotterdam, but it sees hardly any use today. The current structure dates to 1740 and stands out for the typical construction methods of that era, in which the lock walls are made of wood rather than brick. This construction is complemented by wooden yokes. The first records of a lock at this site go back to 1621, while later documents from the period between 1683 and 1691 point to necessary maintenance work.
