Rossen – A New Chapter for Mariehamn
Mariehamn is a city where maritime history meets modern progress. As the population grows and demand for housing and vibrant urban spaces increases, Rossen offers a unique opportunity to develop a new district that aligns with the city’s 2040 vision. Located near the city center, Rossen is designed to support sustainable growth while enhancing the city’s identity and livability.
A new dynamic neighborhood shaped by creativity, culture, and community
Rossen will be a dynamic neighborhood shaped by creativity, culture, and community. It will host cultural spaces, student housing, and shared living solutions, while promoting green mobility through car pools, e-bikes, and walkable streets. Sustainability—ecological, social, and economic—will guide every aspect of its development, creating a welcoming environment for all generations.
Connecting heritage with the future
With its industrial and maritime roots, Rossen will preserve the area’s unique character while introducing new energy and innovation. It will link key parts of the city—such as the shoreline, school campus, and cultural landmarks—creating a seamless extension of Mariehamn. Rossen will be more than a new neighborhood; it will be a vibrant meeting place where past and future come together
