An extraordinary example of Byzantine architecture, the Basilica of Saint Vitale was built between 527 & 548.
The massive expanses of colorful and highly detailed mosaics are still breathtaking even after nearly 1500 years.
Here is shown the bowl-shaped vault of the apse with the Redeemer seated on the celestial globe.
