One of the founders of the Groos National Bank, Carl W. Goos (1830-1893) came to Texas from Germany in 1848. The Groos home designed by Alfred Giles, was built in 1880 by John H. Campmann. Porch detailing on the Victorian residence reveals Gothic Revival influence. Occupied until 1948 by descendants of Groos and his wife Hulda (Moureau), the limestone structure was acquired in 1957 by the San Antonio area council of Girl Scouts, Inc. Recorded Texas Historic Landmark --1977.
