I "Bottini"  di Siena

Siena, The “Bottini” Underground Passageways

Siena Urban Underground Waterways

When wandering the medieval streets of Siena, and seeing the water gush up from Fonte Gaia in Piazza del Campo, it is difficult to imagine that underground there is a labyrinth of over 25 kilometres that supplies water to the fountains and wells scattered about the town. This network of underground aqueducts is called the “Bottini”, from buctinus, a term used for the first time in 1226 to indicate the barrel vault of these galleries, usually around 1.80m high and 0.90 m wide. The aqueduct was mainly excavated from the 12th to the 15th century, to make up for the lack of water. The work incorporated a stretch of passageways, known as the Fontanella, which probably originated from Etruscan times. Today it is possible to walk along these passageways, with the rain water flowing along a small channel cut into the walkway until it reaches the fountains.

The “Bottini” network consists of two main branches on two different levels: the main Fontebranda branch (7.5 km), which takes water to Fontebranda from Fontebecci and the Chiarenna branch (area north of Siena) at impressive depths; and the main Fonte Gaia branch, which is longer (15.7 km) and runs nearer the surface, feeding the fountain in Piazza del Campo and other places at lower altitudes.
