Grecia, and its neighboring districts, was previously inhabited by indigenous peoples belonging to the Western Huetar Kingdom.

[5] These discoveries and rewards led to an increase of migration of settlers into the northwest of the Central Valley, looking for unclaimed land to work on.

[5][6] Eventually, the increase of settlements and construction of homes in the territory motivated residents to look for permission from the local government to officially establish the town.

The act allowed travelers to explore past the "other side of the Poas" and construct a settlement they would call Grecia.

[6] Grecia is part of the tourist route of the western region of the Central Valley of Costa Rica, given the existence in the canton of waterfalls, protected areas, and the Catholic church of Nuestra Señora de las Mercedes, which is part of Costa Rica's historical-architectural heritage.

One recounts how the church was donated by some foreign country, and sent to Greece as a gift, but was wrongly shipped to Grecia, Costa Rica.

[10] The Vamos al Parque program, in collaboration with the University of Costa Rica, developed events such as free art, education, and recreation activities for its residents.

The municipality serves every district in the canton and its main responsibility is to administer local services and satisfy the interests of its residents.
