See two of Helsinki’s most avant-garde buildings through the eyes of your architectural historian guide and come away with an eye-opening insider’s view. The façade of the Oodi Central Library boasts a striking undulating shape that celebrates Finland having one of the world’s highest literacy rates. But only a third of the library contains books, the rest being devoted to public spaces such as a recording studio, movie theatre, restaurants and top-floor Citizens’ Balcony. The innovative use of steel beams allowed the middle floor to be built without columns for an unobstructed view from one end to the other. Your guide will also detail the advanced technologies used to construct the Helsinki Music Centre. In particular, you will discover how acoustic technician Yasuhisa Toyota designed the main concert hall in a terraced, vineyard style so the audience surrounds the musicians. Much of the interior is underground to prevent the building from towering above the surrounding ones.
