Built 1927.
The Esperanto Museum of the Austrian National Library is one of the oldest language museums in the world and one of the major institutions of its kind. Since its founding in 1927, the museum has housed an extensive library, which was designated the Department of Planned Languages in 1990. Over 90 years of continuous collecting has resulted in what is today the world's largest specialized library for Esperanto, planned languages, and interlinguistics.
