A unique and intricate style, the tradition of Maya architecture spans several thousands of years. Often, the buildings most dramatic and easily recognizable as Maya are the stepped pyramids from the Terminal Pre-classic period and beyond. Being based on the general Mesoamerican architectural traditions, these pyramids relied on intricate carved stone in order to create a stairstep design.
In the Late Classic Period Yaxchilan was one of the most powerful Maya cities along the course of the Usumacinta, with Piedras Negras as its major rival. Architectural styles in subordinate sites in the Usumacinta region demonstrate clear differences that mark a clear boundary between the two kingdoms.
