The Basilica of Sant'Apollinare Nuovo, located in Ravenna, Italy, is a testament to the religious and artistic history of the region. Erected by the Ostrogothic King Theodoric the Great in the 6th century, it originally served as an Arian church dedicated to "Christ the Redeemer". Over time, it was reconsecrated and renamed, reflecting the shifting religious landscape. Today, it stands as a UNESCO World Heritage Site, renowned for its stunning mosaics that depict various biblical scenes and figures, offering a glimpse into the early Christian and Byzantine art of the period.
