Rimini also has ancient roots: from the monuments dating back to the Roman Empire (the Arch of Augustus, Tiberius Bridge, the amphitheatre and the Surgeon’s House, unique at international level) to traces of the Middle Ages and the Renaissance, such as the 14th century frescoes in the apse of the Church of St Augustine, the Giotto crucifix, the Malatesta Temple and Sismondo Castle.
