Concierge.com's insider take:
Nearly 2,000 years after it was erected by Emperor Marcus Agrippa, the Pantheon is still one of the most impressive buildings in the world. A 141-foot-diameter dome—whose radius perfectly matches its height—looms over the hushed interior, which originally housed a temple to Rome's 12 most important deities. Reconsecrated as a church in A.D. 609, it became the burial place of kings when united Italy was briefly a monarchy. The tomb of Raphael is tucked away in a quiet niche.
Open Mondays through Saturdays 8:30 am to 7:30 pm, Sundays 9 am to 6 pm.
