This 6th century church is plain looking from the street, but gorgeous and peaceful inside. A great place to take a break from the gritty bustle outside. The elaborate gold ceiling details, the artistically simple but colorful floors, the beautiful paintings and frescos and the ancient columns that had savaged for this building combine to impress but not overwhelm. Great views from both the steep,marble staircase in the front and the smaller piazza in back. Don't miss going inside, if the stairs are too daunting, enter via Piazza del Campidoglio. Well worth it!
