The centerpiece at the Mayan Ruins in Coba is Ixmoja or the Nohoch Mul pyramid. The base is believed to have been constructed during the Early Classic period (250 – 550 AD) and the temple on top during the Late Post Classic period (1200 – 1539). Its name means large hill or great mound. But some archeologists distinguish between the mound at right, which they call the Great Platform or the Monjas, and the Great Temple on the left built on this hill of stones.
