The Church of San Francesco is a real hidden gem. Behind a modest 17th-century marble facade tucked between later buildings hides a typical 13th-century Franciscan church with a mixture of late Romanesque and early Italian Gothic styles. The building has a single nave with several chapels, a very tall truss ceiling and fabulous stained-glass windows behind the main altar that stretch the height of the apse.
Highlights inside the church include frescoes in the choir by Taddeo Gaddi, the tomb of Count Ugolino della Gherardesca in the second chapel in the right transept and the 14th-century cloister. It’s also interesting to note that Cimabue’s Maestà was made for this church, which is now on display at the Louvre Museum in Paris.
