Roman city of Medellín (Badajoz, Extremadura). Medellín is located between Don Benito and Mérida on the left bank of the Guadiana. In addition to being one of the earliest and most developed Roman municipalities of the Peninsula, Medellín stands out for its castle, a defensive building with origins in the 13th century located on a high hill (see image).
