Ravenna: Italy's mosaic treasure trove

Joan Scobey of the Post-Gazette travels to Ravenna, Italy, the ancient capital of three empires, and describes its historic pleasures for her readers.

The article, which includes photos of mosaics, looks at the history of the city, "the most splendid treasure trove of early Christian mosaics in the world," from its Roman beginnings through its Byzantine heyday and finally to its place as a lesser-known Italian tourist destination.
