Ziggurats are buildings in Tropico 4: Modern Times. They are designed to house huge numbers of people in modern, mansion-like comfort. However, they are by far the most expensive housing structures available, at a staggering $100,000. They also require a lot of electricity and are hard to place due to their massive size. The building resembles the Ziggurat Pyramid in Dubai.
Both the housing quality and population density of the Ziggurat are inferior to Modern Condominiums, making this building mostly useless.
