Templo I, the Templo del Gran Jaguar (Temple of the Grand Jaguar), was built to honor – and bury – Ah Cacao. The king may have worked out the plans for the building himself, but it was actually erected above his tomb by his son, who succeeded him to the throne in AD 734. The king's rich burial goods included stingray spines, which were used for ritual bloodletting, 180 jade objects, pearls and 90 pieces of bone carved with hieroglyphs. At the top of the 44m-high temple is a small enclosure of three rooms covered by a corbeled arch. The sapodilla-wood lintels over the doors were richly carved; one of them was removed and is now in the Basel Museum für Völkerkunde. The lofty roofcomb that crowned the temple was originally adorned with reliefs and bright paint. When it's illuminated by the afternoon sun, it is still possible to make out the figure of a seated dignitary. Although climbing to the top of Templo I is prohibited, the views from Templo II just across the way are nearly as awe-inspiring. Templo II, also known as the Temple of the Masks, was at one time almost as high as Templo I, but it now measures only 38m without its roofcomb.
