Three major achievements of the Mayan civilization were in architecture, astronomy and math. The Maya people were great builders who constructed roads, great cities and temples. Mayan cities had magnificent palaces, monuments with intricate designs and temple pyramids that are still evident today.
Pyramid temples, which were constructed for their gods, often incorporated elements of advanced Mayan astronomy, such as the temple of Chichen Itza. The Maya were skilled astronomers that understood astrological cycles, which was important for agriculture and the planting of crops. Calendar making was related to astronomy, and the Maya created round and long calendars. The Maya also were good mathematicians and had a numbering system, which was 20-based.
Some other achievements were their writing system and artworks. Although the Mayan civilization was more than 2000 years old, many of these achievements occurred during 300 to 900 A.D., which was their Classic Period. The Mayan civilization flourished in parts of Mexico and Central America.
