The ruins were built by the German brewer brothers Carl and Emil Hermann in the late 1890s as an enjoyable project to curb their wives’ homesickness to the hills of the Rhine Valley, in those days, ‘sprinkled’ with ruins. Two ruins were erected, one in bricks with large ballrooms. The other one was made of blasted rocks, left over from the construction of a water reservoir. Water was pumped up from the Baltic Sea with a pinwheel down on the beach - in the reservoir they had seals!
