characteristic high ceilings and narrow passageways. The Palace was equipped with numerous large baths and saunas which were supplied with fresh water by an intricate water system. An aqueduct, constructed of great stone blocks with a three-meter-high vault, diverts the Otulum River to flow underneath the main plaza. The Palace is the largest building complex in Palenque measuring 97 meters by 73 meters at its base. Other notable buildings The Temple of the Skull has a skull on one of the pillars. Temple XIII contained the Tomb of the Red Queen, an unknown noble woman, possibly the wife of Pakal, discovered in 1994. The remains in the sarcophagus were completely covered with a bright red powder made of cinnabar. The Temple of The Jaguar (a.k.a. The Temple of the Beautiful Relief) at a distance of some 200 meters south of the main group of temples; its name came from the elaborate bas-relief carving of a king seated on a throne in the form of a jaguar. Structure XII with a bas-relief carving of the God of Death. Temple of the Count another elegant Classic Palenque temple, which got its name from the fact that early explorer Jean Frederic Waldeck lived in the building for some time, and Waldeck claimed to be a count. The site also has a number of other temples, tombs, and elite residences, some a good distance from the center of the site, a court for playing the Mesoamerican Ballgame, and an interesting stone bridge over the Otulum River some distance below the Aqueduct. Modern investigations After de la Nada's brief account of the ruins, no attention was paid to them until 1773 when one Don Ramon de Ordoñez y Aguilar examined Palenque and sent a report to the Capitan General in Antigua Guatemala, a further examination was made in 1784 saying that the ruins were of particular interest, so two years later surveyor and architect Antonio Bernasconi was sent with a small military force under Colonel Antonio del Río to examine the site in more detail. Del Rio's forces smashed through several walls to see what could be found, doing a fair amount of damage to the Palace, while Bernasconi made the first map of the site as well as drawing copies of a few of the bas-relief figures and sculptures. Draughtsman Luciano Castañeda made more drawings in 1807, and a book on Palenque, Descriptions of
