The Giuliano Ghelli Museum is located inside the church and convent of Santa Maria del Gesù in San Casciano in Val di Pesa, in the province of Florence.

In 2008, it was expanded with new rooms created from the premises of the ancient Benedictine nuns' convent, who inhabited it from the 17th to the 19th century. The church remains part of the museum itinerary.

The museum is divided into three sections: a section of sacred art, an archaeological section, and more recently, a contemporary art section has been added.

The section of sacred art displays numerous works from the churches in the area, such as San Michele Arcangelo and storie della sua leggenda by Coppo di Marcovaldo.

The archaeological section exhibits the artifacts found in the San Casciano area, ranging from the world of Etruscan princes from the 7th century BC to the Roman era, showcasing objects of daily and domestic use.

Lastly, the contemporary art section offers a selection of works produced by artists who were mostly active in the area and who have been hosted over the years in the spaces of the Ghelli Museum.
