The Sar is a river in Galicia, Spain.[1] Rising near Santiago de Compostela, it flows through the A Maía valley for over 30km (20miles) before entering the Ulla River, near Padron.
Pomponius Mela (d. 45 AD) mentions it (Sars) in De situ orbis libri III. Galician local poet Rosalía de Castro wrote a well-known collection titled En las Orillas del Sar ("On the Banks of the Sar"), in Castilian Spanish.
