A surprising discovery awaits beneath the surface of Valkenburg: the Roman Catacombs, a unique museum where you can descend into a meticulous reconstruction of the catacombs of ancient Rome. At the beginning of the 20th century, architect Pierre Cuypers Jr. had this subterranean world carved out of the marlstone hill as a tribute to the early Christian burial places of Rome. The corridors, chapels, and burial niches have been recreated with impressive precision. Murals, frescoes, reliefs, and symbols bring the atmosphere of early Christianity to life. As you walk through the cool, candlelit tunnels, it feels as if you've truly traveled back in time. The museum offers guided tours that highlight not only the religious but also the art history and craftsmanship of this reconstruction. Tip: Wear warm clothing… it stays cool underground, even in summer. The entrance is on Plenkertstraat, within walking distance of Valkenburg's town center and the Open Air Theater. Combine a visit with a walk through the Geuldal or the hillside forests for a day full of contrast between above-ground nature and underground history.

Deep in the marl hills of Valkenburg lie the famous Neolithic flint mines, one of the oldest industrial sites in the Netherlands. People dug marl here as early as 2800 BC to extract flint, a hard rock used for tools such as arrowheads, knives, and axes. The tunnels extend dozens of meters beneath the hill and offer an impressive glimpse into how our distant ancestors shaped their habitat. The mines are unique and offer insights into the daily life and technological knowledge of the first farmers and hunters in South Limburg. Over the centuries, the tunnels have sometimes been flooded, subsided, or partially collapsed, but the traces of mining are still clearly visible. Today, parts of the flint mines can be visited via guided tours or special routes where you can literally follow in the footsteps of people from 5,000 years ago.
