In the 19th century, because of the natural environment of the area, Valkenburg became a holiday destination for the well-to-do in the Netherlands. Tourism developed, especially after in 1853 the railway from Maastricht to Heerlen and Aachen opened. Valkenburg railway station is the oldest surviving station in the Netherlands. In the beginning of the 20th century, Dutch architect Pierre Cuypers lived in Valkenburg for several years. He helped develop tourism by designing a hotel, an open-air theater and a copy of the catacombs of Rome. He also restored the medieval church and designed several tombs and a chapel in Gothic Revival style in a graveyard situated on Cauberg, a steep hill outside the town center.
