The Fortress of Grifalco was completely renovated in the 16th century, during the Medici era. We are at an altitude of 651m above sea level in an area that dominates the entire Valdichiana below and whose occupation has followed one another since Etruscan-Roman times, first as a sacred and defensive area and then as a control and defence zone. From documents we know that as early as 1258 the first example of a fortress was located here, of which only sporadic visions remain in 15th and 16th century paintings, especially in the tondo by Luca Signorelli conserved at the Museum of the Etruscan Academy, and sporadic remains of masonry in the basement of the tower of the present-day keep.
The Renaissance building has a quadrilateral base of trapezoidal shape and is set on four corner bastions of different shapes to better adapt to the roughness of the ground Currently the fortress, owned by the municipality, is open to the public during the summer and is going to be an important center for contemporary art as well as a space used for cultural events.
