From the Wikipedia: "The Bargello, also known as the Palazzo del Bargello, Museo Nazionale del Bargello, or Palazzo del Popolo (Palace of the People), is a former barracks and prison, now an art museum, in Florence, Italy.

The museum houses masterpieces by Michelangelo, such as his Bacchus, Pitti Tondo (or Madonna and Child), Brutus and David-Apollo.[2] Its collection includes Donatello's David and St. George Tabernacle[3] , Vincenzo Gemito's Pescatore ("fisherboy"), Jacopo Sansovino's Bacchus, Giambologna's Architecture and his Mercury and many works from the Della Robbia family. Benvenuto Cellini is represented with his bronze bust of Cosimo I. There are a few works from the Baroque period, notably Gianlorenzo Bernini's 1636-7 Bust of Costanza Bonarelli.

The museum also has a fine collection of ceramics (maiolica), textile, tapestries, ivory, silver, armours and old coins. It also features the competing designs for The Sacrifice of Isaac (Sacrificio di Isacco) that were made by Lorenzo Ghiberti and Filippo Brunelleschi to win the contest for the second set of doors of the Florence Baptistery
