Located within the Porta San Pancrazio on top of the Gianicolo (Janiculum Hill), this museum details the history and the leading personalities of the Roman Republic which survived just a few months in 1849. The museum tells the story of the rise of Italian unification, and the role played by Giuseppe Garibaldi (and others) in the birth of the Italian State, an interesting history little known to many visitors to Rome.

It's a very small museum, with a very long name that literally means "Museum of the Roman Republic and memory of Garibaldi and his followers."  As of 2014, the museum has free admission.  The museum is interactive, with maps, descriptions, and videos, as well as many paintings, prints and memorabilia.  The information is in Italian and in many (but not all) places also in English.

Nearby (Piazzale Giuseppe Garibaldi, on the top of the Janiculum) is the famous equestrian statue of Garibaldi, calmly looking over Rome. But it is the second statue of his Brazilian wife, Anita, that truly inspires -- she's a fireball, with a pistol in one hand and a baby in the other, on a leaping horse – riding side-saddle, no less.
