The Museo Nazionale di San Marco is an art museum located in Florence, Italy. It is housed in the former Dominican convent of San Marco, which was refurbished in the mid-15th century by the famous Renaissance architect Michelozzo. The museum's collection includes many important works from the Renaissance period, including frescoes by Fra Angelico, who lived and worked in the convent between 1436 and 1445.

The museum is organized in several sections, each showcasing different aspects of the art and history of the convent and its inhabitants. The ground floor contains a large number of frescoes by Fra Angelico, including his famous Deposition from the Cross, as well as works by other artists who were associated with the convent, such as Domenico Ghirlandaio.

The upper floors of the museum are dedicated to works from the 16th century, including paintings by Pontormo and Bronzino, and to works from the Baroque period, such as paintings by Giovanni da San Giovanni and Jacopo Vignali. There is also a section dedicated to the works of Beato Angelico, which includes his famous Annunciation.

In addition to its impressive collection of artworks, the museum also houses a large number of historical artifacts from the convent's past, including furniture, manuscripts, and liturgical objects. One of the most interesting sections of the museum is the cell of Fra Savonarola, a famous Dominican friar who lived in the convent in the late 15th century and led a popular religious and political movement in Florence.

The Museo Nazionale di San Marco is a must-visit for anyone interested in the art and history of Florence. Its impressive collection of frescoes, paintings, and historical artifacts offers a unique insight into the life of a Renaissance convent and its inhabitants.
