Every year on the first Sunday in August, the flags of many nations fly on the battlements of Rheinfels Castle, the time has come for the Hansen to celebrate the Hansen Festival and welcome new Hansen brothers into the order. This is where the Hansa family from all over the world meets for the annual convention, across national and continental borders, to cultivate customs and friendships.

According to old tradition, the Hansungen are made at the neck iron. Two guarantors stand by the stranger and pledge themselves to him.
