The Theresa entered the national limelight in 1960 when Cuban premier Fidel Castro chose to stay at the hotel while visiting New York to speak at the United Nations General Assembly; while at the Theresa, Castro hosted a visit from Soviet premier Nikita Khrushchev. The Hotel Theresa, built in 1912-13, is significant in the history of Harlem, America’s most prominent African-American community, as one of the most important social centers of that community. It is a major work by the noted architectural firm of George & Edward Blum, exemplifying this firm’s singular approach to ornamentation and inventive use of terra-cotta.
