Work has begun at the Latvian National Library in Riga, Latvia.
Designed by Latvian-born architect Gunnar Birkerts, the $300m building had been delayed by two decades due to funding deficiencies.
Birkerts' original design an asymmetrical glass clad-building, which is inspired by a Latvian folktale, has been retained while some interior changes have been made.
The 13-storey library will feature stainless-steel walls and roofs, and will house six million books.
The project will be complete in 2012, according to archrecord.construction.com.
