Ravenna – Home of CGR Manufactuing


Nestled just on the eastern edge of the Emilia-Romagna region, a few miles from the Adriatic Sea, you will find the ancient city of Ravenna. Once a thriving seaport and covered in marshes, Ravenna now lies five miles inland but remains connected to the sea by the Candiano Canal. Wandering through the unassuming town today, you’d never imagine that for a three century span beginning in 402, Ravenna served as a capital of the Western Roman Empire, chief city of the Ostrogoth Kingdom of Italy, and a nexus of a powerful Byzantine exarchate.

During this prolonged golden age, while the rest of the Italian peninsula flailed in the wake of Barbarian invasions, Ravenna became a fertile art studio for skilled craftsmen who covered the city’s terracotta brick churches in heartrendingly beautiful mosaics. The town is home to one of the most dazzling collections of early Christian mosaic artwork, preserved from the influences of the Renaissance and Baroque era due largely to the city’s remoteness. Even Dante Alighieri himself pulled inspiration from the mosaics of Ravenna. 

The Mausoleo di Galla Placidia– a Roman queen’s unused mausoleum– boasts the town’s oldest mosaics. One particular scene shows San Lorenzo facing leaping flames and is said to have been the inspiration behind Dante’s ‘Inferno.’


Dante was exiled from Florence in 1302 and eventually made his way to Ravenna.  He once described the artwork as a ‘symphony of color’ and surrounded by colorful mosaics  he finished Paradiso– the third and final part of the Divine Comedy. He spent the last few years of his life admiring Ravenna’s masterpieces and eventually died in the city. Many locals say his ghost still wanders about the streets of Ravenna. Today, you can find the tomb of Dante cast in a soft light by a single oil lamp that burns continuously– the oil a gift from the exiled poet’s guilt-ridden hometown of Florence. 


The charming Italian town is world renowned for its preserved 5th-6th century churches and buildings filled with splendid Christian mosaics. Nowadays, it’s an industrial city that has become home to a whole new group of craftsmen. Ravenna now houses the state-of-the-art manufacturing plant of CGR Ghinassi, a company that believes in the highest quality of workmanship and quality.
