The Latvian National Library is the brainchild of American-Latvian architect Gunnar Birkerts, who is perhaps best known for his creations in the United States which include the Corning Museum of Glass in New York State and the Law Library Building at the University of Michigan. Its shape is a symbolic expression of the Hill of Glass and the Castle of Light found in Latvian folklore. Legend has it that the Castle of Light sank into an ancient lake and would only arise from the depths when Latvians were once again masters of their own land. The building is open to the public and it hosts a variety of exhibitions, concerts and events. You can take a guided tour of the building, which allows you access to the top floor, or just get a visitor's pass and wander around for spectacular views of Old Riga across the river.
