The Sauer Castle was the residence of Anton Sauer. Sauer had married his wife Francesca in Vienna, Austria at age 18 and a half. There, they had their five children: Gustave O.L., Anthony Philip Jr., Julius J., Emil, and Johanna.
In 1858 they decided to move to New York City to be with Anton's mother and sisters that had already been there for some time.
