Oulu’s central library, ‘Keskustakirjasto Saari’, is a waterfront cultural landmark that has recently undergone a major renovation. The library is part of a nationally significant built cultural environment (RKY) and represents a restrained form of modernist concrete rationalism. Completed in 1982, the library was designed by Marjatta and Martti Jaatinen as part of the administrative and cultural complex on Vänmanninsaari, which also includes the adjacent city theatre. The ensemble is based on a general design competition held in the 1960s.

The aim of the renovation was to restore the library’s architectural quality to its original status, preserve its most significant spaces, and update its functionality and building systems to meet contemporary standards. The interior emphasises openness, transparency, and carefully selected materials. From a heritage conservation perspective, the most significant spaces include the entrance lobby, the sculptural concrete main staircase, and the high-ceilinged library hall on the second floor. The glass walls surrounding the main staircase offer views between different floors and functions.

JKMM Architects also designed the interiors, respecting the principles of the original architecture and Studio Nurmesniemi’s furnishings. The building’s material palette combines fair-faced concrete walls, mosaic concrete tiles, aluminium, glass, and ash wood. The hard surfaces are contrasted by warm wooden elements and vibrant furniture colours. Varied sightlines, spatial sequences, and natural light remain central to the spatial experience. From the high library hall on the second floor, there are views of Oulu Market Square and a new botanical artwork by Urho Kähkönen to be planted in front of the library – Blue Island brings a living, seasonal artistic element to the outdoor space.

The overall result is an architecturally cohesive cultural environment where history and the present day meet.

The renovated library is scheduled to open to the public at the end of 2025.
