San Andrés es uno de los centros prehispánicos más grandes de El Salvador. Diferentes momentos de ocupación prehispánica se distinguen aquí: el periodo Preclásico Medio (700 a.C. a 250 d.C.), el Clásico Tardío (600 d.C. a 900-1000 d.C.), y durante el Posclásico (900-1200 d.C.). Sin embargo, de estos tres periodos de ocupación maya, el más importante ocurrió durante el Clásico Tardío por la complejidad social y el avance cultural que alcanzó en su momento.
