Chichén Itzá, Mexico
Deep in the Mexican state of Yucatán lies Chichen Itza, a historic Mayan city built between the 9th and 12th centuries. Constructed by the pre-Columbian Mayan tribe Itzá, the city includes a series of monuments and temples. The most celebrated is El Castillo, also known as the Temple of Kukulcan. It is a huge step pyramid in the center of the city which was built as a devotional temple to the god Kukulkan. [1]
