Viikki library is a branch library of Helsinki city library, and it is a part of Infocenter Korona, which was built in 1999 on Viikki campus area. The building is very modern and easily recognisable because of its round shape and blue glass surface. Ecological matters have been considered in the design, and the building is surrounded by a double wall, which conserves energy. The speciality of the building are the three winter gardens which are open to all visitors for reading and recreation.
