Venantonio City was a major city on planet Venantonio. Much like the rest of Venantonio, it was rarely discussed by outsiders because of its notorious stench, acid filled canals and its Amoeboid infestation. The Opera House was once the crown jewel of the city; however, it appears to have fallen into decline. Qwark claimed to have save the city from several disasters; however, given Qwark's habit of lying, its unlikely to be based on fact.
