Linz, Austria

Linz is Upper Austria's capital and the country's third-largest city — a Danube river port that has remade itself into a UNESCO City of Media Arts around the Ars Electronica Center, the Lentos Kunstmuseum and the Anton-Bruckner-anchored Brucknerhaus, all within walking distance of the baroque Hauptplatz and the Pöstlingbergbahn that climbs to the basilica above the city.
