The cultured traveller in Europe

Thanks to Library Stuff for highlighting this article in the New York Times written with the 'cultured traveller' in mind.  Readers are recommended to visit European city libraries because they offer 'respite' from the crowds.  Hopefully this is not a euphemistic way of saying they are underused.Libraries recommended include the Austrian National Library in Vienna and the Strahov Monastery and Library in Prague.  If you feel your European library could benefit from cultured visitors from overseas, why not add in your own recommendations in the comments field on the New York Times website?  And share your suggestions here too!
