Francine Prose writes about three quiet – and very different – Roman museums in an article in the New York Times’ travel section.  Of the three, the most likely to have a few other visitors is the Galleria Doria Pamphilj on Via del Corso.  It is housed in the family’s palazzo and gathers, in a baroque and sumptuous setting, paintings from the Pamphilij collections, including a very familiar Velazquez portrait of Pope Innocent X.  Prose points out that even though the collection contains works by masters such as Caravaggio and Titian, one can discover many other artists with whom one is less familiar.  Prose goes on to describe the strange and empty Museo delle Anime del Purgatorio in the church of Sacro Cuore which she finds affecting and powerful.  Her final stop, in this article is at the Centrale Montemartini.  It’s an old electrical power station from the early 20th century which now houses an amazing collection of Greek and Roman statues and mosaics.  It’s an Art Deco industrial space with much of its original interior preserved and its juxtaposition with the ancient art is truly brilliant.  As a bonus, it really is one place, that even at the height of the summer tourist season, is cool and where one is likely to be almost alone.
