Reinosa
Reinosa lies beside the upper Ebro in the mountain country of Campoo, where routes from Castile approach the Cantabrian coast. Its market brought together the people of the surrounding valleys. In the eighteenth century a new royal road was cut through the difficult terrain to Santander, opening in 1753. Castilian wool and flour could then reach the port more readily, and Reinosa grew as a place where goods were stored and moved on their way to the sea.
