At the heart of Ancient Mayan cities existed the largest plazas. They contained governmental and religious buildings, such as the royal acropolis, great pyramid temples, and occasionally ball-courts. Temples and observatories were always constructed so they followed the Mayan interpretation of the orbits of the stars. Outside of this center were less important temples and shrines. At the outskirts lay the homes of the common people.
The Ancient Mayans grew a wide variety of crops, including corn, manioc, and sunflower seeds. These crops were grown in permanent raised fields, terraccing, forest gardens, and managed fallows. There was also harvesting of wild crops. The Mayans ground cacao and mixed it with water to make the first chocolate.
The Ancient Mayans wrote using a series of glyphs (carved figures or characters), which were painted on ceramics, walls, or bark-paper codices (books), carved in wood or stone, or molded in stucco. Each glyph represented a word. Mayans wrote numbers vertically.
