In Linz, situated on the Danube River, you can feel the pulse of Upper Austria. The city boasts a history that dates back to the Celts, who called it "Oppidum Lentos". "Lentia" was the name the Romans gave to the fort they erected there, complete with a bridge over the Danube. In the Middle Ages, Linz was for a short time the seat of the German Emperor, but it has remained the capital of Upper Austria throughout. The well-preserved edifices dating from the city's medieval period are correspondingly imposing. Most of the old buildings from this time are located in the central historic district. Overlooking it all is the castle of Linz, a baroque structure built on ancient foundations that today houses the Castle Museum.
