Tikal
Although this city-state was partly formed during the Maya Preclassic period, it is best known for the urban development it achieved during the Classic period and for its constant struggles with its rival city, Calakmul, now located in present-day Mexico. For nearly 1,000 years, successive kings were buried—particularly in the North Acropolis—until a later political shift led elite individuals to be buried at the site known as the Lost World (Mundo Perdido). Naturally, this city is striking for the beauty and refinement of its temple architecture, whose roof combs rise above the emerging jungle canopy. In addition, the city experienced a Mexican invasion by the Teotihuacanos in the mid-4th century, which permanently transformed the hereditary dynasty as well as religious and cultural aspects. One can even observe how the architectural style itself changed due to Mexican acculturation in this Maya city.
