The Grotta delle Nottole is situated on Monte Nerone, in the western Marche. The interest in this site came out of the desire to understand aspects the rituals undertaken by the ancient Bronze Age populations in natural cavities. The first research was undertaken between 2001 and 2005. After a period of interruption, work resumed in 2013. This cavern is part of the group of caves in the Sentino gorge, with elements suggesting relationships with the Grotta Nuova fascies along the mid-Tyrrhenian belt, with use until the late Bronze Age. The cave was used periodically, and there were no burials or occupation evidence, which together with the presence of numerous hearths in a chamber dominated by dripping waters, suggests that it had a cult function.
