A brooding example of Baroque style, the palace houses part of the 16th- and 17th-century sections of the collection of the Galleria Nazionale d'Arte Antica and is across the road from the Villa Farnesina. Among the most famous paintings in this large, dark collection are Guido Reni's Beatrice Cenci and Caravaggio's St. John the Baptist. Stop in, if only to climb the 17th-century stone staircase, itself a drama of architectural shadows and sculptural voids. Behind the palazzo is the Orto Botanico, Rome's main botanical park, an attractive oasis of greenery that was once part of the palace's extensive grounds. The garden is known for an impressive collection of orchids, ferns, and cacti, but it's also just a peaceful, green park where kids can run and play. It's open Tuesday through Saturday, 9:30 to 6:30 (5:30 in winter); admission is EUR 2.50.
