The Basilica di Sant'Apollinare Nuovo is an early Christian church located in Ravenna, Italy. The church was built in the early 6th century by Theodoric the Great as a palatine church for his court. It is one of eight structures in Ravenna that are listed as UNESCO World Heritage Sites.

The exterior of the church is relatively plain, but the interior is adorned with stunning mosaics that cover the walls and ceilings. The mosaics were created in the Byzantine style and depict scenes from the Bible and the life of Christ. The most famous of these mosaics is the procession of the Magi, which covers the entire wall of the nave.

Other notable features of the church include the marble columns that line the nave and the apse, which is adorned with a mosaic of the Transfiguration. The church also houses the tomb of Saint Apollinaris, the patron saint of Ravenna.

Over the centuries, the church has undergone numerous renovations and restorations. The most recent restoration was completed in the early 21st century and focused on the mosaics and the preservation of the church's structural integrity. Today, the Basilica di Sant'Apollinare Nuovo is open to the public for visits and religious services.
