This is the exterior of the church and convent of San Marco, the famous Dominican convent and home of my favorite artist, Bl. Fra Angelico (who was not buried there though, but here in Rome at the church of Santa Maria sopra Minerva). The church was closed when I went there and I didn't get back there again, so I never saw the inside of the church itself. That's ok, I think the convent is the better of the two (Fra Angelico-ly speaking that is :)
