The lock Blankenstein , even Hoffstiepel called, is a last surviving gate from the period of navigability of the Ruhr by King Friedrich II.

It was built between 1777 and 1778 and is one of a total of 16 locks that were built for navigation on the Ruhr between 1776 and 1780 . It is 58 meters long, 10 meters wide and has a stroke of 3.8 meters. The lock chamber is 44.5 meters long and 5.4 meters wide. Gatekeepers house and lock are under since August 24, 1988 listed . The lock is currently no longer functional, but has been renovated since 2014.

The Stiepel waterworks has been located on the lock island since around 1870 and a hydropower plant for operating the drinking water pumps since 1910 . The production amounts to 16 million cubic meters of water per year. The drinking water is pumped from a groundwater well near the Ruhr, cleaned of suspended matter using a multi-layer filter system, then deacidified and chlorinated.

A pipeline model (main water line to the house connection) from the Ruhr water educational trail has been set up in front of the lock house. Information on the subject of ecology and water extraction is conveyed using display boards .

The Blankenstein lock is part of the route of industrial culture .
