El Castell de Falgars (Beuda, la Garrotxa): a Roman Republican watchtower in north-east Hispania Citerior

Abstract El Castell de Falgars (Beuda, la Garrotxa) is a circular watchtower built in the late Republic, during the Romanization of Hispania, which controls a wide territory of the current Province of Girona (Catalonia). The present paper analyses the causes that led to its construction, as well as the reasons for its rapid abandonment before the end of the first century BC. It also describes the phases of reoccupation of the building during the second half of the third century AD and in the Middle Ages, detected through archaeological excavations carried out at the site between 2010 and 2012.
