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 a detail of the bust of Christ from the middle of the intrados.
