There is a Palatine Antiquarian Museum in which collected artifacts, ceramics, frescoes, mosaics, inscriptions, sculptures and portrait heads actually found on the hill in the excavations are displayed. It was built on the site of Domitian's palace which was the largest palace in Rome for 3 centuries. Remains of Domitian's palace survive on either side. It is a pleasant and interesting museum, especially if you have read up on your history first, and it is not an overwhelming size.
The House of Augustus in 2006 and the possible Lupercal Cave in 2007, I don't know about you, but I am wishing I were an archeologist in Rome today.
