Pons Fabricius

The Pons Fabricius (Italian: Ponte Fabricio, "Fabrician Bridge") or Ponte dei Quattro Capi, is the oldest Roman bridge in Rome, Italy, still existing in its original state.[1] Built in 62 BC, it spans half of the Tiber River, from the Campus Martius on the east side to Tiber Island in the middle (the Pons Cestius is west of the island). Quattro Capi ("four heads") refers to the two marble pillars of the two-faced Janus herms on the parapet, which were moved here from the nearby Church of St Gregory (Monte Savello) in the 14th century.[2]

According to Dio Cassius, the bridge was built in 62 BC, the year after Cicero was consul, to replace an earlier wooden bridge destroyed by fire. It was commissioned by Lucius Fabricius, the curator of the roads and a member of the gens Fabricia of Rome. Completely intact from Roman antiquity, it has been in continuous use ever since.

The Pons Fabricius has a length of 62 m, and is 5.5 m wide. It is constructed from two wide arches, supported by a central pillar in the middle of the stream. Its core is constructed of tuff. Its outer facing today is made of bricks and travertine.


CIL VI, 1305, the inscription on the bridge

An original inscription on the travertine commemorates its builder in Latin: L . FABRICIVS . C . F . CVR . VIAR | FACIVNDVM . COERAVIT | IDEMQVE | PROBAVIT ("Lucius Fabricius, son of Gaius, superintendent of the roads, took care and likewise approved that it be built"). It is repeated four times, once on each side of each arch.

A later inscription, in smaller lettering, records that the bridge was restored under Pope Innocent XI, probably in 1679.
