A view of the sun temple from above at the ancient site of Machu Pichu in the Cusco region of Peru. The sun temple was dedicated to the solar god and patron Incan deity, Inti. The temple was an important observatory in which the measurement of the solstices was undertaken. Underneath the Sun Temple is a cave-like room named the Royal Tomb in which the nobles and possible the Sapa Inca, ruler of the Cusco Empire and later the Inca Empire, were laid to rest in their mummified state.
