Participants will also experience Madrid through field visits showcasing some of the city’s most innovative municipal projects – “from the playful to the practical”.
Attendees may choose to visit Madrid Río, a linear park that was created by burying a major highway and now stretches along the Manzanares River; CaixaForum, a former power station that has been transformed into a cultural centre; Madrid in Game, an incubator that provides training and support to entrepreneurs and developers to position the city a leader in the field of video games; or Valdemingómez Technology Park, a facility where the city converts urban waste into enough energy to power 550 buses and 35,000 homes.
For more than a decade, CityLab summits have convened the most influential mayors and voices from hundreds of cities worldwide. Past CityLab conferences have been hosted in New York, Los Angeles, London, Miami, Paris, Detroit, Washington DC, Mexico City, and Amsterdam.
