Creating Helsinki Christmas lighting through co-design and citizen involvement


Helsinki uses co-design project methods to commit all the stakeholders and entrepreneurs in order to make the city a distinctive and coherent Christmas Lighting City. Through co-designing, the City of Helsinki will be aware of the most desirable decorative themes, which central locations to allocate for new Christmas Lighting and the ways even the smallest shops could join this winter celebration of design theme. The aim is to also help and encourage participants to make Helsinki an attractive holiday city by guiding them throughout the whole process, from voting for lighting ornaments to building and storage.
