🧵 5,000 YEARS AGO, A CITY IN SOUTH ASIA HAD SOMETHING MANY MODERN CITIES STILL STRUGGLE WITH: SANITATION.
This was Mohenjo-daro.
Built around 2500 BCE in present-day Sindh, Pakistan, it became one of the greatest cities of the Indus Valley Civilization.
And its city planners were remarkably sophisticated.
The streets were laid out in an organized grid, with major roads intersecting at near-right angles.
But the real surprise was underground.
🏠 Many houses had bathrooms.
🧱 Wastewater was carried through carefully constructed covered brick drains.
🚰 The city had an extensive drainage and sanitation system.
For a civilization that flourished roughly 4,500–5,000 years ago, that is extraordinary.
Then there was the Great Bath—a large, carefully sealed public water tank that may have played an important ritual or social role.
Mohenjo-daro wasn't just a collection of ancient houses.
It was a planned urban center with sophisticated architecture, water management, craft production, trade, and public infrastructure.
At its height, tens of thousands of people may have lived there.
Then, centuries later, the city was abandoned.
And here's the mystery:
We still don't fully understand why.
Environmental change, shifting rivers, declining trade, and other factors have all been proposed—but there is no single universally accepted explanation.
The ruins were excavated in the 1920s, revealing one of the ancient world's most fascinating urban civilizations.

🧵 A WHOLE CITY DISAPPEARED INTO THE SEA… AND THE WORLD FORGOT IT EXISTED. 🌊
More than 1,000 years ago, one of ancient Egypt’s most important cities vanished beneath the Mediterranean.
Its name?
Thonis-Heracleion.
Long before Alexandria became Egypt’s famous Mediterranean gateway, Thonis-Heracleion was one of the country’s most important ports.
Ships arriving from the Greek world were required to pass through the city before entering Egypt.
Merchants, sailors, priests, and travelers passed through its busy harbor, making it a major center of trade, religion, and cultural exchange.
Ancient writers, including Herodotus, mentioned the city.
And its legends were even more fascinating.
According to ancient traditions, Heracles was said to have first entered Africa at this location, while Helen of Troy was supposedly connected to the city in one of the ancient stories surrounding her.
Then something extraordinary happened.
Over centuries, earthquakes, tsunamis, rising sea levels, and soil liquefaction weakened the ground.
Eventually, the city sank beneath the Mediterranean.
By around the 8th century CE, Thonis-Heracleion had disappeared beneath the water.
For centuries, people could only read about it in ancient texts.
Then archaeologists found it.
Beneath the sea were temples, statues, jewelry, coins, pottery, ship remains, and inscriptions—a buried snapshot of ancient Egyptian life.
A city once filled with merchants and sailors had become an underwater archaeological site.
🌊 Imagine living in a city that would one day disappear beneath the sea—and being completely forgotten for centuries.
History is stranger than fiction.
Would you have believed this city existed if archaeologists hadn't found it?
