Thonis, also known as Thonis-Heracleion, was an ancient Egyptian city located near the Nile Delta. It served as a significant trading port and was known for its temples and vibrant commerce. The city was dedicated to the god Hercules, and it played a crucial role in connecting Egypt with the Mediterranean world. In the 8th century BCE, Thonis thrived as a bustling hub for merchants and travelers. However, by the 2nd century CE, the city began to decline and eventually sank into the sea, becoming submerged under water. Its ruins were rediscovered in the early 2000s, revealing valuable artifacts and insights into ancient Egyptian civilization.
