The City of Turku established the Baltic Sea House (BSH) in August 2008. The organisations who share the same premises are Centrum Balticum, Baltic Region Healthy Cities Association, UBC Environment and Sustainable Development Secretariat and Valonia, Service Centre for Sustainable Development and Energy Issues of Southwest Finland. The association and the UBC Environmental and Sustainable Development Secretariat have already shared the same premises since 2006. The organisations working at the BSH have a strong competence to support the strategic development on health and sustainable development in the city level. Collaboration with the actors in BSH became visible during the Opening ceremony and the Mayors Meeting which was organised in August 2008 in conjunction with the celebrations of the Associations 10th anniversary.

New project applications of the Association, UBC and other BSH actors are prepared and the collaboration will focus especially on the Aalborg Charter and Commitments.
