Siena Cathedral - Inside
The cathedral (Duomo di Siena) was simply beautiful outside and downright spectacular on the inside. According to Wikipedia, it was built between 1215 - 1263. It was serendipidious, since that was the small window of time when Moorish was all the rage in architechture. That meant striking black and white marble stripes everywhere!
There was also a magnificent library with original frescos from 1500.
