The Metropol Parasol project in Seville, Spain transformed a derelict plaza through the construction of six large timber "parasols" or mushrooms that provide shade. The 30m tall structures were inspired by the cathedral's vaulted domes and form one of the largest timber structures ever built. The parasols have had a major social and commercial impact, revitalizing the once neglected area by providing space for a market, performances, and restaurant that attract visitors and residents. The project turned an empty lot into a vibrant public space that is now full of activity and local pride.
