Piazza Garibaldi is the main square in Casalmaggiore and represents the heart of the city, since "il Listone" (the name given to the central marble paving) is a regular gathering place for the locals.

This is where all of the city streets converge, following an urban plan that places this square in the centre.

It should be of no surprise that this is where the weekly market is held every Saturday, along with major outdoor events such as the Fair of Piazza di Spagna and the Fair of San Carlo.

The large square (measuring 96 metres x 38 metres) was created in the 17th century, precisely in 1618, in a marshy place that served as the original town centre. When the Palazzo Comunale (Town Hall) was built here in 1788 the square was divided into two parts, creating Piazza Turati behind the building and delineating the current Piazza Garibaldi in the space in front of the building.

The city's most fascinating historic sites are almost all located around the square, such as the Diotti Museum or the Bijou Museum or even the Estense Tower, the only remaining part of the fortified Renaissance complex.
