A mosaic from the San Vitale in Ravenna, depicting the emperor Justinianus who reigned the (eastern) empire 527-565 AD.
An on the other side was his empresses.
The bishop seat in the same basilica. Kinda looks like a throne, doesn't it? It's probably very intentionally.
The paintings in the dome, redone during the baroque.
One of the many round campaniles in the city which makes for an excellent shot.
