Augustobriga was a Roman town in Hispania Tarraconensis established on the site of the Celtiberian settlement of Arekorataz. Mentioned in the Antonine Itinerary, it stood on the route connecting Caesaraugusta (Zaragoza) and Asturica Augusta (Astorga). Its remains lie beneath the modern village of Muro de Ágreda in the province of Soria, where sections of the Roman walls and other archaeological remains have been identified.
