In 1905, Harriman's founders established the American Temperance University to promote their social doctrine. The building is referred to as The Temperance Building and is one of Harriman’s most beloved historical landmarks. It is listed on the National Historic Registry. The Temperance heritage was slow to depart. There was no liquor store in Harriman until 1993. The city of Harriman has been able to maintain many of the original town buildings including The Princess Theatre, one of only a few Art Deco theatres still standing today. Town guests can visit Harriman's Carnegie Library, one of the few remaining buildings in the country originally funded by philanthropist Andrew Carnegie.
