Stuttgart's Public Library is extraordinary

Stuttgart’s Public Library is nothing short of spectacular. Designed by Yi Architects in 1999 after winning a competition for the project, they chose to express the importance of this cultural centre by giving the building a grand physical presence. 
Completed in 2011, the building takes the form of a cube fully constructed out of pale grey fair-faced concrete. Standing at five-stories, the square shaped gallery hall is surrounded by a shell of books. The interior is arranged in a spiral, designed to be flowing promenades flooded with light from the glass roof.
