Cloaca Maxima, Ancient sewer in Rome
The Cloaca Maxima is one of the world's earliest sewage systems, constructed in Ancient Rome.
Originally built by the Etruscans as an open-air canal, it was enclosed by the Romans around 600 BC.
It is considered a marvel of engineering and a testament to the advanced infrastructure of Ancient Rome.
Despite being over two thousand years old, parts of the Cloaca Maxima are still in use today.
Legend has it that the Cloaca Maxima was built by the second king of Rome, Ancus Marcius.
