The National Library of Catalunya dates back to 1907. Barcelona’s City hall offered the medieval-era building of the old Hospital de la Santa Cruz to host the National Library in the year 2000.

At the time of writing the library holds around 3 million books and documents.

The Structure’s main claim to fame however may be that it was the place where Barcelona’s own Antoni Gaudi spent the last two days of his life, having been hit by a tram and, due to the famous modernist architect’s dishevelled looks, mistaken for a beggar and given only the bare minimum care until he died in 1926.
