Countless people and foundations in Dortmund work for others, support ideas and carry out projects, in different ways and with great commitment. They assume social responsibility, work for the common good and, through their initiative, promote the development of Dortmund and the surrounding area. Building networks between these individuals and foundations and enabling them to exchange ideas and experiences is the underlying idea of the Dortmund Foundations Day, which was launched by the city of Dortmund in 2016 and is supported, among others, by the Wilo-Foundation as a private sponsor. The event provides a forum for urban society to discuss and develop effective approaches and solutions for tackling social challenges. At the same time, the Dortmund Foundations Day provides a space for interested individuals to learn more about the foundations and their work. The Dortmund foundation portal serves as a digital communication platform: https://www.dortmunder-stiftungsportal.de/.
