The Maya civilization was formed of independent city-states and, consequently, there are regional variations in architecture but almost all buildings were constructed with a precise attention to position and layout and a general style prevails. Multi-level elevated platforms, massive step-pyramids, corbelled roofing, monumental stairways, and exteriors decorated with sculpture and mouldings of Maya glyphs, geometric shapes, and iconography from religion such as serpent masks are all typical features of Maya architecture.
