The Mayans were once the most impressive builders of the new world, but as their technology flourished, it seemed like their architectural spirit moved entirely towards raw functionality, and many of their works became simple stone and concrete structures with very little in the way of beauty, embodied by the highly geometric Kukulkanan style. In the XIIth Century however things changed and their Federal King Palenk'ua V brought back the Mayan tradition, rebuilding the Conglomerate's capital and constructing many of the finest works which now stand in the city. His efforts created a new trend within the Mayan government, renewing the aestheticism which had once moved Mayan architects.
