Camino Real de Tierra Adentro
El Camino Real de Tierra Adentro, also called the Silver Route, was a Spanish road that stretched 2,560 kilometers (1,590 miles) from Mexico City to San Juan Pueblo (Ohkay Owingeh), New Mexico (now part of the United States). It was used from 1598 to 1882 and was the northernmost of four major roads that connected Mexico City to important areas during and after the Spanish colonial period. In 2010, 55 sites and five existing UNESCO World Heritage Sites along the Mexican part of the route were added together to the World Heritage List.
