Tik'al was the capital of the most powerful kingdoms of the ancient Maya.  It dates back to the 4th century B.C. and is located in Guatamala.  Tikal Temple I is considered a tomb for the ruler Jasaw Chan K'awiil.  The temple's steep staircase rises nine step levels symbolic of the nine levels of the underworld.
