The castle of Oliveto was built in 1424 on the hills overlooking the valley and Elsa river, adjacent to the road that connects Castelfiorentino to Certaldo.

It is a rectangular red brick construction with high walls and four corner towers crowned with battlements.

[1] The castle has a marble coat of arms at the entrance and a main door that leads into an internal courtyard with a loggia with four arches and a chapel for religious functions.

The castle is well preserved with fifteenth-century furniture, trophy weapons, and a collection of portraits executed from the sixteenth to the eighteenth century.

[1][2] In the third season of Medici (TV Series), Girolamo Riario's men seize Ferrara, 100 miles from Florence and takes their salt.
