Ireland has a 5,700-year-old man-made lake
In the heart of Ireland lies Lough Boora, a 1.5 kmē lake created by Neolithic farmers around 2800 BC. Using wooden staves and earthworks, they constructed a massive dam to control water levels and create a stable water source for their crops. This ancient feat of engineering is one of the oldest examples of a man-made lake in Europe, predating the pyramids of Egypt by over 1,000 years. Archaeologists have confirmed the site through excavation and radiocarbon dating, verifying the remarkable age of this remarkable feat.
