Just south of El Castillo is the Temple of the Initial Series. Not much is known about Templo de la Serie Inicial. However, it is famous among archeologists based on the explorations of John Lloyd Stevens in the mid-19th century. He discovered a stela which is a large carved stone. Tulum Stela 1 shows a Mayan king surrounded by Mayan hieroglyphs (script). This limestone pillar dates from 564 AD, hundreds of years before Tulum was built. The historic artifact is now exhibited in London’s British Museum.
