Castellet de Banyoles

The Castellet de Banyoles is an ancient Iberian city and archaeological site near the River Ebro in Tivissa, in the Ribera d'Ebre region of Catalonia. Built around the first half of the 4th century BCE on a headland reached only through a narrow entrance, it is known for the pentagonal towers flanking that entrance, unique among the protohistoric fortifications of the Iberian Peninsula, and for a treasure of decorated silver and gold vessels found in 1927. It was destroyed in a Roman siege, possibly during the revolts of Indibil and Mandonius (206–205 BCE) or, most likely, during the campaign of Cato the Elder in 195 BCE, and traces of the Roman camp lie outside its walls.
