The Segni Project is a long-term research initiative between the BSR and the Archaeological Museum of the Comune di Segni. Since 2011, research has focused on understanding the development of the settlement with the aim of placing the known monuments into the wider context of the urban plan. Between 2012 and 2014 the project undertook a series of excavations at three locations in the city: alongside the magnificently preserved Temple of Juno Moneta, at Prato Felici on the eastern side of the acropolis and in the central location of Piazza Santa Maria.
The excavations at Prato Felici led to the discovery of a monumental cistern, measuring 36.7m in length and 12.62m in width, dated to mid-second century BC. Excavations in Piazza Santa Maria, in front of the cathedral of Santa Maria Assunta, investigated the multiple phases of occupation of the Latin town, and led to the discovery of a Roman house with a fine polychrome mosaic, dated to the 1st century BC.
More recently, the BSR has participated in the excavation, recording and conservation of the nymphaeum of Q. Mutius. Dated to the late 2nd-early first century BC, the nymphaeum is remarkable thanks to a mosaic Greek inscription above the pool, recording the architect responsible for the monument. The Segni Project has led to numerous publications, and the final monograph of the excavation is now in preparation.
