Boldt Castle with a sad love story is located on the heart-shaped island of one of the world-famous Qiandao Lake, located on the border of the United States and Canada. It is like a fairy tale fairyland. The castle is a Valentine's gift to his beloved wife from the New York hotel rich in the late nineteenth century. But most of the project was carried out, and his wife died suddenly. George has not returned to the island since then, leaving it to his descendants, this Rhine-style castle.
