The historical centre is enclosed by completely intact and beautifully preserved medieval walls.
Once in the centre, it’s well worth visiting the Piazza del Duomo, also called Piazza Dante. The remarkable white and pink marble facade of the San Lorenzo Cathedral built in the twelfth century, is particularly eye-catching and is the most important monument of the city.
The inside of the cathedral is in the shape of a Latin cross, with a nave ending in a semicircular apse, and two side aisles. There are also various intriguing sculptures, such as the impressive marble baptismal font by Antonio Ghini.
Don’t miss the Cassero Senese, one of four ramparts built along the city walls, alongside that of St. Peter, the Sienese rampart and the entrance tower. It was built during the domination of the Sienese Republic and was completed in 1345. The Church and Convent of San Francesco, found along the walk through the ramparts, is also worth a visit.
A great way to discover the city’s mysterious and deeply historic secrets is to visit the The Museum of Maremma Archaeology and Art. The Polo culturale Le Clarisse is also in Grosseto’s historic centre, and is home to both the new Gianfranco Luzzetti Museum - whose collection includes painting and sculpture masterpieces dating back to the 14th and 19th centuries - and the Clarisse Arte exhibition space, which is primarily for contemporary exhibitions but also holds a documentation centre. Finally, we recommend a visit to the Natural History Museum of Maremma with various relics, rocks, minerals and environmental reconstructions.
