Founded in 1912, Cloister occupies a neo-Gothic building on Prospect Avenue, between Cap and Gown Club and Charter Club. Cloister closed temporarily in 1972, becoming open to all Princeton alumni, before reopening as an undergraduate club in 1977. The club is "sign-in", meaning that it selects its members from a lottery process rather than the bicker process used by several of the eating clubs. Cloister typically attracts an athletic crowd and its members often include a number of Olympians. The official motto of the club is “Where everybody knows your name”.
Cloister Inn was founded in 1912. The present building was constructed in 1924.
More recently, Cloister received mention in Ian Caldwell and Dustin Thomason's 2004 bestselling novel The Rule of Four. Caldwell, a 1998 graduate of Princeton, was a member of Cloister.
