Puente de Piedra the (Bridge of Stone) in Spanish but known as the Bridge of Eggs is a bridge in Lima, Peru in South America. It was built in 1608 by the architect Juan del Corral to link Lima with Rímac. It was the only link between the two banks of the Rímac River until President José Balta's construction programme starting in 1868.
The Bridge gets its name from the stone masonry mortar which was believed to have been mixed with egg whites from sea birds to improve its consistency.
