Guatavita Lake (laguna de la Guatavita) which is also close by is a circular lake in what appears to be a meteor crater. However, the origins of the crater are unclear. Lake Guatavita was one of the sacred lakes of the Muiscas, where they celebrated a ceremony in which the chief (The Zipa) was covered in gold before bathing in its waters. This is one of the origins of the legend of El Dorado. Guatavita today bears a curious notch in its cliffside, evidence of an attempt to drain the lake by the conquistadores in 1580.
