Books, however, are not what pull tourists into this library, but the big garden, rich and unique that lies above. This is not a library, nor a park, but a hybrid building, innovative and groundbreaking.
The library attracts many tourists, plant enthusiasts as well, who come to enjoy the beautiful roof with the botanical garden. The garden opened on June 2002, and is one of the largest roof gardens in Europe, having two different floors. The building and garden intertwine, in a harmonizing way, both from the inside and out, a combination of light and darkness and between restriction and freedom.
The big library (10,000 square meters) was built by the architectural duo Marek Budzynski and Zbigniew Badowski with the landscape architect Irena Bajerska, after winning a competition to design the building in 1993. They presented a whole new design concept, that fit the changing political, cultural and financial scene at the time, after being under Communist rule until 1989.
The whole building is covered in climbing plants, and is a great example of energy conservation and green building. The roof is open from Spring to Fall. From the roof you can see the view of the city landscape, and of passersby on the streets below.
There is an abundance of attractions that work well with the pretty building, like a stream, coy pond, fountains, bridges, seating areas, walking trails, greenery, granite sculpture and viewing areas.
