Guayabo National Monument is an archaeological site in which the remains of a very highly developed pre-Columbian city can be seen. Today Costa Rica is highly cosmopolitan. Costa Ricans are predominantly Catholic, but freedom of religion is protected by the constitution, and the Protestant community is quite important. There is a Catholic Church in every city or town. Fiestas, dances, and other cutural and religious events take place around the church, where people gather to socialize or simply enjoy the clear night-time sky.
Traditions are very important to the Costa Rican people.
Religious holidays are among the most festive occasions, especially that of August 2nd, when thousands of Costa Ricans pay homage to the Virgen de los Angeles. The northern region of Guanacaste has provided many of the country's folk traditions. Colorful wooden ox-carts are an enduring part of rural Costa Rican scenery, used to carry agricultural products. During colonial times they were actually the most important means of transportation. Folk dances from the provinces of Cartago and Heredia are also notable elements of folk culture.
