History
Cayey was founded on August 17, 1773, by Juan Mata Vázquez, who became its first mayor. It is popularly said that Cayey derives its name from the Taíno word for "a place of waters". It was named in honor of Miguel de Muesas, the then governor of Puerto Rico. The town is located in a valley nestled between Puerto Rico's Cordillera Central mountain range and the Sierra de Cayey at roughly the midpoint of routes PR-1 and PR-52.

An education base began in the early to mid-1950s when the Interamerican University opened a branch in Cayey providing teacher training through a night class scheme. In 1967 the University of Puerto Rico opened a campus in the former Henry Barracks Military Reservation, and in the early 1980s El Turabo University, subsidiary of the Ana G.
