7. The Record-Breaking Giants of Congo Basin

Scientists have found what might be the highest termite mounds in the world right in the middle of the Congo Basin; some examples stand an amazing 42 feet (12.8 meters). Built by Macrotermes species, these enormous constructions epitomize termite architectural excellence. The mounds’ several chambers, sophisticated ventilation systems, and sophisticated structural support help them to keep their amazing height. Estimated to be over 10 million individual termites, these enormous buildings have taken decades to reach their present scale. Especially in the design of sustainable buildings with natural ventilation systems, the engineering ideas used in these constructions have motivated human architects and engineers.
