One of the most anticipated events this spring in May involves architectural orienteering, architects’ clinics and walking tours. Digital doors will open to the clock tower of the Helsinki Railway Station designed by Eliel Saarinen, the studio of Yrjö Kukkapuro and YLE’s link tower, for example. Guided tours lead architecture lovers all the way from the Mall of Tripla to Töölö and Helsinki in the 1920s.
