Lubaantun
Located near San Pedro Columbia Village, Lubaantun is the largest Maya archaeological site in the south, and was one of the last major settlements built in Belize prior to the collapse of the Maya. This short lived Late Classic site, was built and occupied from 730 AD to 890 AD.
Temple walls were constructed of cut stone, fit without the use of mortar. The largest structure at Lubaantun rises 36 feet above the plaza floor. There are eleven major structures grouped around five main plazas and three ball courts. The controversial "Crystal Skull" was found here in 1926.
Tikal
The greatest of all Classic Mayan cities is located in Guatemala, about 50 miles northwest of the Belize/Guatemala border. Set in the jungle canopy, the site today consists of over 3,000 buildings, including a handful of impressively tall temples that tower above the forest. The site of Tikal is a national park, where the native flora and fauna still flourish relatively undisturbed. In addition to its numerous well-excavated temples and pyramids, Tikal presents an excellent opportunity for animal and bird watching. Along the paths, spider and howler monkeys, gray foxes and red coatis are visible to the visitor. The combination of archaeological remains and the natural environment of the Peten makes Tikal the only place in the world that has been declared both a Natural and Cultural Heritage for Humanity.
