 Alpha Chi Alpha ( " Alpha Chi " ) was founded in 1956 as the Phi Nu chapter of Alpha Chi Rho , a national fraternal organization . A previous Phi Nu chapter of Alpha Chi Rho at Dartmouth had merged with the Kappa chapter of Phi Kappa Sigma in 1935 to become Gamma Delta Chi , a local fraternity still in existence at Dartmouth . The second Phi Nu chapter of Alpha Chi Rho is unrelated to the first chapter . The men of Alpha Chi Rho again broke away from the national group in 1963 and became a local fraternity named Alpha Chi Alpha . The Dartmouth chapter objected to a clause in the national fraternity organization 's constitution that required all Alpha Chi Rho brothers to " accept Jesus as their lord and savior . " The land and house used by the Alpha Chi Alpha fraternity are owned by the college . Dartmouth invested $ 1 @.@ 3 Million in renovations completed in the fall of 2004 , which included the razing of the " Barn " structure that was used as social space by the brothers of Alpha Chi Alpha to make way for a new expanded basement and main floor area . Renovations on the Alpha Chi Alpha physical plant were completed in 2005 .
