The impact of indigenous peoples on modern Costa Rican culture has been relatively small compared to other nations, since the country lacked a strong native civilization to begin with. Most of the native population was absorbed into the Spanish-speaking colonial society through inter-marriage, except for some small remnants, the most significant of which are the Bribri and Boruca tribes who still inhabit the mountains of the Cordillera de Talamanca, in the southeastern part of Costa Rica, near the frontier with Panama.
