This paper presents the results of the 2015 excavation in the necropolis of Monte Li Santi at the Faliscan site of Narce. Our knowledge of the necropolis was based until now mainly on the 1894 publication in the Monumenti Antichi dei Lincei. During the 2015 excavation, three large rock-cut chamber tombs were discovered, unfortunately already looted, together with a series of niches near them, used probably for ritual practices. In the different sections of this paper, the authors discuss the history of the research, the stratigraphy, the finds, the few human remains discovered and the process of conservation of the finds.
