150 years of colourful history
Representing Renaissance revival architecture, Mannerheimintie 6 is a unique historic building with a colorful history dating back more than 150 years. Originally built in 1870 as a boys’ school, this stone castle located in Helsinki’s busiest commercial area has since housed art dealer Gösta Stenman’s palace of art. A spectacular entrance staircase, a room height of up to five meters, and Viennese-style halls with massive arched windows make this building captivating and unique.
At the heart of everything
You can’t resist the appeal of this top location – direct access to the heart of Helsinki means the best services and amenities are always at your fingertips. Across the street is the iconic department store Stockmann, and the Esplanade Park, with its high-quality restaurants and luxury boutiques, is also within walking distance. This is where you live and breathe city life without compromise. All central downtown services, universities, hotels, key museums, and cultural sites are just a short walk away. A close by underground tunnel network provides covered access to local transport stations and services, enhancing connectivity and convenience.
