12 marble statutes which were once part of the Auximum Foro line the courtyard of the seventeenth century Town Hall. These are the famous 12 headless statutes thanks to which Osimo is known as the “town of the headless ".
Some sections of the ancient Roman walls are still visible while the Magna Fount where according to legend Pompeo Magno watered his horses also dates to Roman times. The Romanesque Cathedral was also built on a Roman building.
The town today is entirely mediaeval with Palazzos and Romanesque and Gothic churches such as the Church of St. Mark with its painting of the Madonna and Saints by Guercino.
Well worth a visit is the Sanctuary of St. Giuseppe da Copertino (where the body of the Saint is worshipped), which is one of the most beautiful monuments of the town.
