I accidentally visited on a day when there was some sort of literature festival--there were various stages and tents set-up where readings were taking place.
One of the most-visited museums in the world, and included in the book 1,000 Things to See Before You Die, the Louisiana Museum of Modern Art has a wonderful collection as well as stunning views of the Øresund Sound. Denmark's best art museum was established in 1958, and lies 20 miles north of Copenhagen.
