Acqueduct Odescalchi –  Ferriere.

Historical heritage analysis.
Location: Bracciano, Italy.
University: Università degli studi Roma La Sapienza.
Site: Historical heritage


The stretch of the aqueduct that we have examined, is part of a complex system partly underground and partly visible, which develops within the City of Bracciano in the north of Rome. It was built under Livio Odescalchi reign in 1696 for the production of energy needed by the craftsmanship of the city (foundries, paper mills and tanneries).

The shape of the arch shows many similarities with Trajan’s Aqueduct, which is located in the estate of Vicarello and reach into Rome. Indeed it is well-known that both aqueducts, coming from the same source of the Fiora, were restored by order of Paul V in the seventeenth century. Surely the construction system of the aqueduct Odescalchi were inspired to hydraulic ancient Rome, as the labour had very close examples. As well as the Roman aqueducts, the aqueduct Odescalchi, flows underground for several km until the village of Boccalupo. Re-emerges in the locality Fontanilaccio to 90 meters with its characterised massive masonry, mortar topped up. This construction technology is present in the entire aqueduct. The underground parts, the conduit (or shape) is made from waterproofed masonry, with mortar of lime and pozzolana end. The aqueduct emerges in the resort of Via Principe of Naples. Three round arches and one to the top of the sixth characterize this stretch; the latter assumed different shapes to allow the passage of the wagons. The arches in the section studied, are smaller than the 3 arches of the others that powered the mill.

The analysis reveals the importance historical heritage of the site in advanced status of abandon. We especially detected the follows conservation problems: disintegration of the plaster, resumption of the plaster with cement mortar, growth of weeds on the walls, development of root systems of trees, growth of lichen on the mortars and growth of moss on masonry.
