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 constructive programme starting in 1868.
The Bridge gets its name from the stone masonry mortar which was believed to have been mixed with the whites of 10,000 sea birds' eggs used in the construction. Arches and buttresses also support the bridge construction.
