Tomba della Mula, Tholos tomb in Sesto Fiorentino, Italy

Tomba della Mula is a tholos tomb with a false dome, located at via della Mula 2 in Sesto Fiorentino. Its dome-shaped roof spans about 9 metres in diameter, and unlike the nearby Tomba della Montagnola it has no central pillar: the walls curve from ground level up to close at the top. Part of its dromos, the access passage, was demolished when the tomb was incorporated into Villa Garbi Pecchioli.

The tomb, a 7th-century BC tholos, has been known since at least the 15th century, when it was incorporated into the present Villa Garbi Pecchioli, also called Villa Mula, as a wine cellar. That conversion modified the floor and demolished part of the dromos, the access passage. It was declared a national monument in 1905.

The name comes from a Tuscan folk rhyme: "Tra Quinto, Sesto e Colonnata, una mula d'oro c'è sotterrata" — between Quinto, Sesto and Colonnata a golden mule lies buried. It echoes the Etruscan and Roman treasures occasionally unearthed in these fields. Since the 15th century the tomb has been used as the cellar of Villa Garbi Pecchioli, also called Villa Mula.

The tomb sits at via della Mula 2 in Sesto Fiorentino, about 9 m across, and was built into the cellars of Villa Garbi Pecchioli, so it is reached through the villa rather than from open ground. Part of the original dromos, the entrance corridor, was demolished when the floor was altered, so the approach is shorter than the Etruscan one. It has been a national monument since 1905.

This is the largest pre-Roman Italic dome tomb ever identified in Italy. The construction without center supports shows how advanced the ancient Etruscans were at engineering.
