Rome's Art & Architecture: Our Guide
"The Pantheon is one of those sites that first-time visitors absolutely must see and repeat visitors will likely find themselves drawn back to again and again—partly because it's so majestic and partly because there's so much to see and do around it. It will be crowded throughout the day; get there early morning when crowds are thinner so that you can really appreciate the engineering of its open-domed ceiling and rotunda with less distractions." - Laura Itzkowitz
