Medina del Campo - Valladolid - Castilla y León Mota Castle. 15th century Built with concrete tinged between brick cladding, taking advantage of the earlier remains of the thirteenth and fourteenth centuries. Work began on John II, and Henry IV would finish the work of the interior enclosure with the large Tower of Homage more than 40 meters high. Subsequently, the Catholic Monarchs would endow the castle with a large defensive barrier with an underground shooting gallery and scant the surrounding moat. It was declared a National Monument in 1904.
