According to this website, the Craig House was built for the Civil War officer General Joseph Howland in 1859, and called Tioranda, and was turned into America’s first privately licensed psychiatric hospital in 1915.  It was closed in 1999.

According to this website, the Tioranda School was built in 1865 by designed by Frederick Clarke Withers, a famous gothic architect.  The building operated as a school, a chapel, and event a medical treatment space during the Great Flu Epidemic of 1918.

I don’t know anything about the house I found on the property and also photographed here, but I presume it is related to the estate.
