Florence’s main square is located on the site of the city’s ancient Roman Forum, which later became the market square dedicated to commerce while the Piazza del Duomo was the center of religious and civic affairs and Piazza della Signoria was the city’s political heart. A warren of narrow lanes crowded with buildings, churches, towers, and palaces sprang up in the area surrounding the market square, a portion of which became the Jewish ghetto. Today’s sweeping space was created by razing almost all of this neighborhood as part of a 19th-century urban renewal project during the brief period when Florence was capital of the newly united nation of Italy. Today the only original architectural detail that remains is the 15th-century Colonna dell'Abbondanza, marking the historic center of the square.
Piazza della Repubblica is generally included in private or small-group Florence walking tours, or Florence tours by Segway or electric bike. In addition to this landmark square, skip-the-line Florence highlights tours may include the Uffizi Gallery, Ponte Vecchio, Michelangelo’s David statue in the Accademia Gallery (Galleria dell'Accademia), Piazzale Michelangelo, Palazzo Vecchio, the Florence Duomo, and Santa Croce (Basilica di Santa Croce).
