Completely refurbished and reopened in April 2004, Rheinfels Castle in St. Goar on the Rhine offers a modular event concept in Germany’s biggest castle ruin. Under the motto Rent-a-Castle events for up to 2,000 people can be staged in the big castle tent or Europe’s biggest vaults. The 4-star hotel with 61 rooms and space for 310 meeting-goers will add a spa and a wine bar in the vaults from autumn 2004. www.schloss-rheinfels.de
