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. The routes lead to a popular drive that provides panoramic views of the island from its highest points. Puerto Rico was ceded by Spain in the aftermath of the Spanish–American War under the terms of the Treaty of Paris of 1898 and became a territory of the United States. In 1899, the United States Department of War conducted a census of Puerto Rico finding that the population of Cayey was 14,442. 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. Mendez conglomerate opened a campus in the old tobacco factory at the entrance of town. The Interamerican University will be opening a Graduate campus in front of the main town square (downtown), and there are conversations with a foreign educational concern to open a technology campus using the buildings left over by the Gordonshire Knitting Mills. There are three major private schools: Radians School, the long established Colegio de Nuestra Senora de la Merced and La Milagrosa School. Cayey's health care base expanded in the mid-1960s with the Mennonite Medical Center and a Municipal Hospital along with laboratories,…
