Cultural heritage is beneficial in society for the many social and cultural processes and practices through which people engage both with the past and with contemporary and future societies. It can bring people together, make them engage with each other and their values, stimulate learning, enhance well-being, generate meaning, create employment, etc. But cultural heritage also bears risks and can have negative impacts, for example when it divides communities, advances hate and prejudice, discourages innovation, and prevents development. An important task of managing heritage is the challenge of reconstructing or regenerating heritage processes and practices that promise to benefit the living and their descendants while preventing harm. The chapter argues that historical reconstruction should invest more attention in managing processes and practices of tangible and intangible heritage for the benefit of present and future generations. The continuously needed regeneration of cultural heritage requires us to embrace change and transformation in various ways.
