#fidenae

In 27 AD, a Roman amphitheater in Fidenae was jammed with 50,000 spectators. The builder had cut corners on the foundation supporting the seats. The amphitheater collapsed killing more than 20,000 people. The Roman Senate then required amphitheaters to be inspected and certified by government officials before opening to the public. The architect of infamy was named Atilius, and he was banished from the Roman Empire.
