The environmental work Nocturnal came about as part of the plan for the Arabianmäki Park in Helsinki at the end of the 1990s. The work's grey-steel pillars are joined together by metal structures attached to their upper sections. The pillars also serve as lights, are 7.5 metres tall, and are grouped around a paved square. The work serves as a meditative element situated between the Arabia factory building and the industrial arts centre, and between the park and the wooden buildings on the other side of Hämeentie Road.
