Mémorial Albert Ier, memorial located in Liège

The Mémorial Albert Ier is a 42-metre tower of pale grey stone on the tip of Monsin island, between the Meuse and the Albert canal. Its shaft is faced with flat rectangular panels of blue stone and topped by a glazed lantern; a standing figure of King Albert I in a long coat is set against the base. Two statues of a dockworker and a puddler guard the retaining wall leading from the Marexhe bridge.

The memorial was built in 1939 to honor King Albert I, who had recently passed away. The site marked the region's development through the Albert canal, constructed from the 1930s onward to establish Liège as a major trading hub.

Above the lighthouse door are the national motto "L'union fait la force" and a heraldic lion, both engraved by Oscar Berchmans, who also cut the canal diagram into the stone. The two statues flanking the esplanade wall, by Robert Massart and Louis Dupont, depict a dockworker and a puddler, the trades of the Liège steel port.

Access to the tip of Monsin island is via the Marexhe bridge; a retaining wall bridges the height difference between the bridge and the peninsula, opening onto the esplanade that leads to the lighthouse. The 42-metre tower rises above the flat terrain, with the king's statue set against it. The site is outdoors and unstaffed, so visits depend on daylight and weather.

The memorial originally housed a functioning lighthouse that guided ships on the Meuse river at night, and its light signals also aided airplane navigation. This practical purpose made it more than a commemorative site, integrating it into the region's working infrastructure.
