Biebrich Palace, a magnificent three-winged baroque building, was built between 1700 and 1750 directly on the banks of the Rhine. It was the residence of the princes and later dukes of Nassau. Today, the rotunda and galleries serve as representative rooms for the Hessian Minister President. Every year at Whitsun, the renowned "International Riding and Driving Tournament" takes place in the beautiful castle park.

Civil wedding ceremonies are held in the rotunda. It has barrier-free access and offers space for 60 people.

After the ceremony, couples can use the castle park for photos and a small champagne reception. Unfortunately, the interior of the castle cannot be used for this - even in bad weather.
