Ricina

Ricina is an ancient town of Picenum, Italy, 5 km NW of the modern Macerata, on the banks of the River Potenza, in a fertile valley. It was probably a municipium until it was refounded by Pertinax and Septimius Severus, after which it bore the name Colonia Helvia Ricina Pertinax. The site is now deserted, but considerable ruins of a theatre and remains of baths and other buildings (all in brickwork of the Imperial period) still exist; also the fragments of an ancient bridge over the Potenza. Flavian of Ricina was a bishop here in the 3rd century.
