67. Ravenna is truly a Byzantine jewel!

The small city of Ravenna on the east coast of Italy, is truly a jewel. Ravenna boasts 8 Unesco World Heritage Monuments, each of which display the Byzantine Era's most significant art form, mosaics. Not only did mosaic tiles beautify a building, they also instructed the illiterate with their depictions. A visit to Ravenna is a treat since it's somewhat off the tourist radar, therefore you can share one of these monuments with only a few other new converts of mosaic art.
