Lichtenberg Castle ruins

On the eastern flank of the St. Pietersberg hill (overlooking the Meuse), lies a very special and valuable point of interest: the Lichtenberg Castle ruins. 
It is undoubtedly the oldest castle ruin in the Netherlands, with foundations dating from the 10th century. 
The more built-up sections date from the 12th and 15th century and are made from sandstone and marl respectively. From the top, visitors have a breathtaking view of the Meuse Valley.
