Medina de Rioseco
During the 16th century Medina del Campo thrived, with its fair becoming the most important among the triangle of great Castilian fairs (Medina del Campo, Villalón and Medina de Rioseco). The fair of Medina del Campo featured a notable presence of international dealers, chiefly Castilian, Portuguese, Italian (Genovese, Milanese and Florentines) and Flemish, as well as also some French, English and German merchants.
