Colombia has a long history dating back before the Spanish conquest. Some indigenous ruins still exist today, such as stone monoliths and underground burial chambers. Colombia has experienced strong economic growth in recent decades but wealth is unequally distributed and poverty and unemployment remain issues. Colombian culture blends indigenous, Spanish, African and other influences. Some of Colombia's most emblematic cities are Bogota, Medellin, Cartagena, and Barranquilla, which are notable for their cultural offerings and festivals. Typical Colombian foods include bandeja paisa, tamales, sancocho, and cazuela. Famous Colombians include artist Fernando Botero, writer Gabriel Garcia Marquez,
