In the 16th century, Medina de Rioseco experienced an economic boom as it became a trading center for silver arriving from India via the port of Seville. Donations and legacies from America increased the city's wealth. Four large churches were built.

Located on the highest point of the town. Its construction began at the end of the 15th century, replacing an earlier building. Its style is late Gothic, with Renaissance and Baroque additions, such as the tower, rebuilt in 1700 when the previous one collapsed.

Unfortunately the church was locked, so that I could not see the alligator skin, kept inside since the 18th century.
