This beautiful and unique fountain was designed and built by Dominican friar Fray Rodrigo de León in the 1560s. It incorporates Mudéjar, Gothic and Renaissance elements into a harmonious whole. The interplay of octagonal forms reflects Moorish designs typical of southern Spain. The octagonal pool at the center of the fountain is surrounded by an arcade of decorative mudéjar style brick work. This inner arcade is covered by a ribbed vault supported by eight substantial flying buttresses, both Gothic elements. And the exterior of the dome is crowned by a blind lantern, a Renaissance touch.
