The pre-Romanesque church of Santa Eufemia de Ambía holds the classification of Bien de Interés Cultural, and was declared a Historical-Artistic Monument in 1931. It reflects a great Mozarabic influence and has a close relationship with the churches of Santa Comba de Bande and San Miguel de Celanova, as its activity was promoted by the Monastery of Celanova. Its structure consists of a single rectangular nave, although it may have originally had three naves separated by arcades. It has three chapels, which were once separated by horseshoe arches, of which only some remains, two Roman altars, and a medieval wooden carving of a crucified Christ remain today. Outside, we find the so-called “Fountain of the Nymphs” where the Roman altars, now inside the temple, were previously located.
