The Basilica of Sant’Apollinare Nuovo is a UNESCO World Heritage Site located in the historic center of Ravenna, Italy. It was built by the Ostrogothic king Theodoric the Great in the 6th century as his palace chapel, and later converted to Catholicism by the Byzantine emperor Justinian I. The church is famous for its stunning mosaics, which cover the side walls and depict scenes from the life of Christ, as well as saints, prophets, and angels. The mosaics are remarkable for their use of gold, color, and perspective, and for their blend of Eastern and Western artistic influences. Travellers who visit the church can admire the mosaics, as well as the 24 columns with Corinthian capitals, the Ambo, and the relics of Saint Apollinaris, the first bishop of Ravenna and the patron saint of the city.
