There are two competing stories about where the name came from.
On tasting a local wine from a plain cup, Emperor Theodosius’ daughter, Galla Placidia, said “Oh wine, this crude goblet is not worthy; I would drink you from a cup of gold” (berti in oro, in Italian).
According to an other theory, the name Bertinoro derives from the Latin britannorum, to remember the British monks who lived here in the distant past.
The town has rejoiced in its splendid castle, the defensive fortification that looms over the entire valley, since the Middle Ages, when Bertinoro deferred to the city of Ravenna. The Holy Roman Emperor controlled it from 1177 until Italian unification in 1861.
