History

Frederick II Tower is a medieval military tower in San Miniato, Italy, built by Frederick II of Swabia between 1217 and 1223. It completed defensive works begun under Otto I, the tenth-century Holy Roman Emperor associated with consolidating imperial authority in Italy. From its position above the town, the tower helped control movement between Florence and Pisa and along the Via Francigena, a major medieval route for pilgrims and travelers heading toward Rome.

Imperial construction

The tower stood on the highest of San Miniato’s three hills and formed one of the principal points in the town’s fortifications. The wider defensive arrangement included Matilde Tower, now the cathedral bell tower, and Cornacchie Tower, which was demolished in the eighteenth century. Construction was probably carried out in part by Norman craftsmen. An inscription on the tower stated that Corrado da Spira, an imperial chancellor and senior official in the emperor’s service, supervised the work.

The hill may have contained a Roman command center before the medieval fortress was built, although this remains a traditional belief rather than a confirmed fact. Another tradition associates the tower with Pier della Vigna, Frederick II’s former secretary. After falling from favor amid accusations of treason or corruption, he was said to have been blinded inside the tower.

Abandonment and destruction

Frederick II Tower was abandoned in 1530. Michele Mercati, a naturalist and papal archiater, meaning a senior physician in the papal household, later purchased the tower and the surrounding land and made the property his residence.

The original structure was destroyed during the Second World War. Retreating German troops placed mines inside the tower on 20 July 1944 and detonated them at 22:30 on 23 July. The tower was completely destroyed, but it was faithfully reconstructed in 1958 by the architect Renato Baldi and the engineer Emilio Brizzi. It is recognized as Italian national heritage.

Remains

Tower and hilltop setting

Frederick II Tower is a military structure with a slightly trapezoidal plan and a height of 37 metres. The reconstructed tower stands on a hill 192 metres high, overlooking the section of the Valdarno, the valley of the Arno River in Tuscany, around San Miniato. Its hilltop position formed part of a defensive layout that also included Matilde Tower, now the cathedral bell tower, and the former Cornacchie Tower.

Inscription and reconstruction

An inscription formerly placed on the tower identified Corrado da Spira as the supervisor of its construction. The present building is a faithful 1958 reproduction of the medieval tower, following the complete destruction of the original in 1944.
