I always wondered about the seven wonders of the world. I knew about the others, but never heard of Chichen Itza. Chichen Itza was one of the greatest Mayan centers of the Peninsula. It has many monuments, including the Kukulkan Pyramid (also known as El Castillo) which was elected as one of the new seven wonders of the world on July 7,2007. Chichen Itza means “at the well of Itsa.” Most sources agree that the first word, Chichen, means seven, but there is considerable debate as to the correct translation of Itza. Chichen Itza was constructed around AD 600. It is located in the Yucatan state in Mexico. It is currently the second most visited archeological site of Mexico.
