Teotihuacán
Knowledge of the great ruins of Teotihuacán was never lost. After the fall of the city, various squatters lived on the site. During Aztec times, the city was a place of pilgrimage and identified with the myth of Tollan, the place where the sun was created. Teotihuacán astonished the Spanish conquistadores during the post-conquest era.  Today Teotihuacán is one of the most noted archaeological attractions in Mexico.
