The American Society of Civil Engineers awarded the Guayabo National Monument the International Historic Civil Engineering Landmark Award.
Guayabo Ceremonial Center, Costa Rica was built between 300 B.C. and 1400 A.D.. It is considered the main pre-Columbian archaeological site in Costa Rica. It is believed to reflect a bridge between the Mayans and the Incas.
The Guayabo historic site is situated in the province of Cartago.
The location was nominated by the Costa Rican Engineer and Architects College for its fascinating and still functional aqueducts and cobblestone roads.
This is only the second pre-Columbian site in the Americas to receive such a designation. The first one is Machu Picchu in Peru.
