Although they might not be amongst Rome's top museums, the Villa Torlonia museums and park are interesting to visit. The 19th century villa was once the residence of former dictator Benito Mussolini and inside visitors can see the villa's beautiful frescoes and lavish decor as well as Mussolini memorabilia. The park and gardens are open to the public and there's an art museum housed in the Casina della Civetta, or Owl's bungalow. Ancient Jewish catacombs, believed to be the oldest in Rome, were discovered under the ground but are currently only open by special arrangement.
