Canal de Castilla

The Canal of Castile is a canal in the north of Spain. Constructed between the last half of the 18th century and the first half of the 19th century, it was conceived to facilitate the transportation of wheat from Castille to the ports in the Bay of Biscay for export. The canal runs 207 km through the provinces of Burgos, Palencia and Valladolid, in the Autonomous Community of Castile and León.

The canal was mostly used between 1850 and 1870 but competition with railways saw its use change to irrigation and for powering mills, in the latter part of the 19th century. Navigation ceased in 1959 with the closure of the locks.
