Palazzo Pubblico is a historic building located in the Piazza del Campo, the main square of Siena, Italy. The building dates back to the 13th century and was originally the seat of the government of the Republic of Siena. The Palazzo Pubblico is a beautiful example of Gothic architecture and features a tall bell tower known as the Torre del Mangia.

The Palazzo Pubblico is home to the Civic Museum of Siena, which houses an extensive collection of artwork from the Middle Ages and Renaissance, including frescoes, sculptures, and other decorative arts. One of the most famous works of art in the museum is the Maestà by Simone Martini, a large and detailed fresco depicting the Madonna and Child surrounded by angels and saints.

The Palazzo Pubblico is also famous for its courtyard, known as the Cortile del Podestà, which features a beautiful Gothic-style fountain and a statue of the goddess Athena. Visitors can explore the various rooms and chambers of the building, including the Sala del Mappamondo (Hall of the World Map) and the Sala dei Nove (Hall of the Nine), which features a series of frescoes depicting episodes from the history of Siena.

The Palazzo Pubblico is also adjacent to the Torre del Mangia, which is accessible by climbing a steep spiral staircase. The tower offers stunning views of Siena and the surrounding Tuscan countryside. Visitors can also explore the nearby Fonte Gaia, a large and ornate fountain located in the Piazza del Campo, and the nearby Palazzo Chigi-Saracini, which houses a museum of music.
