The resilience of societies and institutions in the BSR was significantly tested during the COVID pandemic and will face even a greater challenge at the time and after the war in Ukraine. During the last two years it became apparent that in every country the museums, memory and cultural institutions have a much bigger role to play in ensuring resilience in the society during the crises than initially expected. In the "Baltic Museum Resilience" project we shall analyse how the cultural and memory institutions managed and overcame the latest crisis to ensure resilience from three perspectives: governance, business model and digital sustainability and economic sustainability. Based on the best practices already implemented, relevant research and peer reviews we shall develop a toolbox with solutions for the institutions: what and how to do. The toolbox will help to sustain the institutions but also provides additional resilience opportunities for the whole society during a crisis - but the principles could also be applied at any time for improving the organisation's performance and helping to achieve its goals. The toolbox will be piloted and adopted during the project and made available to all respective institutions in the BSR. Our main target groups are authorities (responsible for culture and heritage), NGOs active in the field and SMEs providing innovative services in the area, who will increase their capacities to lead the change to resilient heritage institutions.
