Temple of the Inscriptions is a Mayan ruin in Southern Mexico. It is in the ancient Mayan city of Palenque. This is a modern Spanish name. The ancient name of the city is Lakamha meaning big water. Inside the Temple of Inscriptions was found a stairway leading to a stone slab. Under this slab was found the coffin of Pakal who ruled in the 600s. He had a face mask covering his face which had been made of pieces of jade. Pakal was identified because archeologist learned how to translate the inscriptions in the tomb. After 900 ad the town was abandoned, and became overgrown and hid by vines. The area as of 1930 has been a National Park. It is also a UNESCO World Heritage site.
