Germany's baroque masterpiece, the Bergpark Wilhelmshoehe, has been placed on the UNESCO world heritage site list.

As Europe's largest hillside waterpark, the Bergpark Wilhelmshoehe features waterfalls, secluded ponds and hidden bridges.

"We have received far more inquiries, and more people want to spend the night here to go and discover the Bergpark," said Sonja Tobor at the tourist information office of Kassel, the city that also hosts the famous Documenta art show.
