|The Hiram Bithorn Stadium is statewide significant under Criterion A as the property has been center stage in the sporting, recreational and social development of Puerto Rico. Since its construction in 1962, the Hiram Bithorn Stadium has served as venue for events of great importance such as sports tournaments and professionals practices; amateur tournaments of baseball, basketball and football; intercollegiate games, boxing, wrestling and car competitions. The stadium has been the preferred location for social events such as trade shows, fairs, circuses, conventions; and educational, cultural, recreational, political, and ecumenical activities. The Hiram Bithorn Stadium is also significant under Criterion C in Architecture for its modern mid-20th-century design, which highlights new architectural trends of the moment through the design of its structure, accordion-type roof and building techniques that were beginning to be applied at the time. The structure, elegant and austere, continues today serving Puerto Rico in its full capacity.
