CLEVELAND, Ohio (Aug. 12, 2004)--A Coast Guard boat from Station Alexandria Bay races by the Alster Tower of Boldt Castle. Prussian immigrant, George G. Boldt, had the castle built at the turn of the century on Heart Island for his wife. This tower was the playhouse the Boldt family stayed at while the castle was being built.
