The neighbourhood of Getsemaní in Cartagena is a UNESCO designated world-heritage site. In 2013, Arup and its strategic partners completed a program of social research, quantitative and qualitative data collection, with the aim of developing a design strategy for the area's night time. In 2016, a pilot installation took place to activate one of the neighbourhood’s streets at night, through a community participated design process. Arup lighting designers were joined by social researchers from the London School of Economics, local mobility experts Despacio and strategic partner PLANE_SITE, among many others. The end result has proven that lighting can help transform public perception of urban spaces, while still respecting their unique history and character.
