Austria’s little city of Krems an der Donau would merit a stop in any event, with its pastel-hued old center that still feels authentic, rather than touristy. Recently, it unveiled a new cultural ensemble called the Kunstmeile Krems, or Art Mile, which extends out from the old city’s gate. On our recent visit to the Krems and Wachau valleys, we took a day to explore some of its venues, and I left feeling quite impressed with what Krems has created. The Kunstmeile would be a feather in the cap of a city 10 times as large.
