There's a lake in Africa that's a perfect square - Apparently.
Lake Sidi Yahia, located in Morocco, is a man-made lake that was created in 1907 to supply water to the city of Fes. Due to its unique design, the lake has a square shape, with each side measuring approximately 2.5 kilometers. This unusual shape is a result of the lake's construction, which involved building a series of canals and dams to create a self-contained water system.
