Puente de Piedra, Stone bridge in Lima District, Peru.

Puente de Piedra is a stone bridge over the Rímac River linking Lima's historic centre with the Rímac district. Built of light grey-brown masonry, it has two large arches visible in the photograph, a flat stone deck with a dark metal railing, and black lampposts with white globes on the piers. It carries both pedestrians and vehicles.

The bridge replaced a 16th-century crossing built under viceroy Andrés Hurtado de Mendoza, destroyed by a Rímac flood in 1607. Juan del Corral built the stone bridge in 1610 under viceroy Juan de Mendoza y Luna, Marquis of Montesclaros, at a cost of over 400,000 pesos. Repairs followed in 1808 under viceroy Joaquín de la Pezuela, and in 1902 the bridge was widened to its present form.

Locals also call it Puente Trujillo, after the street it extends, and Puente de Huevo (Egg Bridge), from a mistaken belief that egg whites from sea birds were mixed into the mortar. The bridge marks the start of the Jirón de la Unión, once the city's main street.

Walking across is straightforward and the bridge is accessible during daylight hours, though parking nearby is limited. Early morning or late afternoon offers a quieter experience if you prefer fewer crowds.

Locals call it the Egg Bridge because of a mistaken belief that egg whites from sea birds were mixed into the mortar to harden it. The nickname is recorded in the sources, but the egg-white story is not: the mortar was ordinary stone masonry. The bridge also carries the names Old Bridge and Trujillo Bridge, after the street it continues.
