Hurrah — the "week of culture" is here!
From now until April 17, Italy's state-run museums and sites are free. (Yay!) In Rome, that includes the Colosseum, Forum, Palazzo Massimo, Galleria Borghese (where you can find Raphael's beautiful "Entombment," above) and Baths of Caracalla… to name a few. Take advantage!
Here's a complete list of sites with free entrances this week, from Pierreci (click on the drop-down beneath the map on the right to choose your region — Rome, of course, is Lazio).
