The Tomba della Mula is a beehive tomb in Sesto Fiorentino, near Florence, Central Italy, dating to the 7th century BC.
The name derives from an ancient legend, according to which a golden she-mule had been buried in the fields around Florence. It is known since the 15th century, and is the largest pre-Roman Italic dome tomb known in Italy. The structure has a diameter of some 9 m and contains vaulted roofs. The tomb was declared a national monument in 1905.
