Piazza San Lorenzo, square
Piazza San Lorenzo is a public square in Florence anchored by the Basilica of San Lorenzo, whose large dome rises above the surrounding buildings. The space features daily market stalls, Renaissance-era palaces nearby, and the Osservatorio Ximeniano, a scientific institute from the 1700s that still operates today.
The Basilica of San Lorenzo was founded in 393 CE, making it the oldest church in Florence, and served as the city's main cathedral until the 1600s. The square developed around this sacred site as the Medici family, who ruled Florence for centuries, made it a center of their power and built nearby structures to reflect their influence.
The square takes its name from the ancient basilica at its core, which has served as a spiritual hub for the city for many centuries. You see people moving through daily life here: shopping at outdoor stalls, stopping for coffee, and passing between the historic buildings that frame their routines.
The square is open to pedestrians at all times and free to enter; market stalls operate daily except Sundays and Mondays. Public buses stop nearby, but parking in the area is limited, so walking or using public transport is advisable.
The Osservatorio Ximeniano on the square, founded in the 1750s, remains active today, measuring weather and earthquake data for the region. This scientific function makes the site more than just a historical location, as modern scientific work continues within one of Florence's oldest neighborhoods.
