A Prokaryium is a complex  bacterial city, designed and built solely by microscopic bacterial cells. Each has a population of a few billion. The many different designs are autogenic and develop from a single seed cell. Some even have what appear to be irrigation tubes. The capacity for such complex architecture is embedded into the genome of every cell that makes up these cities. Would love to see architects take inspiration from these optimised bacterial forms .

This Ancient Prokaryium is from a project with Sarah Craske
