The Latvian National Library (LNL)

The building was opened to visitors in 2014 and the people have renamed it the Castle of Light, referring to the poem written by the Latvian poet Auseklis (1850-1879) that stands for a repository of wisdom. The idea underlying the exterior of the building stems from the play The Golden Horse written by Rainis (1865-1929) where the author depicts a glass mountain with a sleeping princess and only the pure-minded Antiņš can ride up the hill and wake the princess.
