Despite its wonderful museum, fancy churches and enormous castle, Barletta is best known for the not-so-colossal Colossus that stands beside the Basilica del Santo Sepolcro on Corso Vittorio Emanuele. No-one knows who the guy in the funny frilly crown really is although he's definitely a Roman Emperor of some sort - Theodosius, Valentinian, Marcian - they just can't decide which one.
