The very first mention of the castle that is today Wasserburg zu Gommern dates as far back as 948, making it one of the oldest castle hotels in the world. Throughout the centuries, the castles was demolished and rebuilt and it changed owners many times. Apart from a royal residence, the castle has also been used as a detention centre, a social home and as a training ground for a state-owned company among other things before being turned into the hotel that it is today.
