Helsinki Stock Exchange Building, Art Nouveau financial building in Kluuvi, Finland
The Helsinki Stock Exchange Building is an office structure with a granite-faced exterior in central Helsinki, designed by Lars Sonck. Its interior is organized through galleries, loggias, and a glass-roofed courtyard that connects offices and creates varied spatial experiences.
The building was completed in 1911 during Finland's period of economic growth and represents a shift away from ornamental styles toward more rational design. Sonck was among the first architects in the country to apply these principles to financial institutions.
The building reflects how Finnish finance and business developed in the early 1900s through its design choices and role in the city. It remains a landmark that shapes the character of the Kluuvi district where it stands.
The building is located at Fabianinkatu 14 near Senate Square and is easily accessible on foot throughout central Helsinki. Since it remains an active office building, exterior viewing is the best way to appreciate its architectural qualities and entrance details.
The building cleverly uses its narrow plot through a vertical arrangement of galleries and loggias that bring light and visual interest to the offices. This solution shows how early Finnish architects creatively solved the challenge of limited urban land.
