King Baudouin Tower, Television and observation tower in Plombières, Belgium.

The King Baudouin Tower is an observation structure located on the Belgian side of Vaalserberg, standing approximately 50 meters tall. The tower combines stairs and elevator access to reach viewing platforms that offer views across the surrounding landscape and the nearby border areas.

The structure was first built in 1970 using recycled components from decommissioned French radar installations. It underwent significant reconstruction in 1993 to achieve its present height and configuration.

The tower is named after King Baudouin, who reigned from 1951 to 1993. At the top, a platform holds a restaurant, and a further staircase leads to its roof. About 50 metres away, the Gemmenich railway tunnel passes through the Vaalserberg.

Visitors should expect variable weather conditions at elevation and dress accordingly for changing climate. Access is straightforward using either stairs or elevator, though the elevator is more convenient for those with mobility considerations.

The tower marks a special geographic point where visitors can see and access three countries from a single location. This tri-border position makes it a rare destination for travelers interested in experiencing Belgian, German, and Dutch territory simultaneously.
