Castellet de Banyoles

The Castellet de Banyoles is an ancient Iberian city and archaeological site dating from the 3rd century BC, located in the modern town of Tivissa near the River Ebro in the Ribera d'Ebre region of Catalonia[1]. The site is famous for its pentagonal towers flanking the entrance, unique among protohistoric fortifications of the Iberian Peninsula[1]. A treasure of silver and gold decorated vessels was discovered in 1927[1]. The settlement was destroyed by a Roman siege, possibly during the Campaign of Cato the Elder, with evidence of a Roman camp identified outside the walled enclosure[1].
