Villa Torlonia is a splendid public villa which faces onto via Nomentana, an important road in Rome. The place where it is located used to be a farming estate until the 18th century; lately, in 1806, the architect Giovanni Valadier started the project of the current villa. The most characteristic and extravagant features of the villa are due to Alessandro Torlonia, who added a series of other buildings from 1832 onwards.

The villa currently looks like an English garden embellished with furnishings and buildings. The monumental entrance to the park is in via Nomentana. If you walk along the park you can admire the medieval Villa, the 1842 pink granite obelisk, the building of the lemon garden, the Neo-Renaissance Villa of the Princes, the Serra Moresca, Campo dei Tonei square, the House of the Owls, the temple to Saturn, the Nymphaeum and the Mews.

In the Noble Casino and in the House of the Owls there are two museums. The second is set in the suggestive liberty style structure of the House of the Owls, with its splendid decorations, mosaics, glass windows and paintings of owls.
