"Santa Maria del Popolo is a Renaissance church at the edge of Piazza del Popolo and just within Rome's 3rd-century walls. It was decorated during Rome's most recent artistic peak, the 15th to 17th centuries, and is packed with masterpieces. The church is free, though some coins will come in handy for turning lights on in chapels. The place mostly draws visitors on the Caravaggio trail. Two canvases painted by that controversial and innovative artist hang in the chapel next to the main altar." - Katie Parla, Maresa Manara
