Trajan's Wall (Valul lui Traian in Romanian) is the name used for several linear earthen fortifications (valla) found across Eastern Europe, in Moldova, Romania, and Ukraine. Contrary to the name and popular belief, the ramparts were not built by Romans during Trajan's reign, but during other imperial periods. Furthermore, the association with the Roman Emperor may be a recent scholarly invention, only entering the imagination of the locals with the national awakening of the 19th century. Medieval Moldavian documents referred to the earthworks as Troian, likely in reference to a mythological hero in the Romanian and Slavic folklore. The other major earthen fortification in Romania, Brazda lui Novac (Novac's Furrow), is also named after a mythological hero.
