Seen as one of Madrid's most beautiful natural spots, Cuenca Alta del Manzanares Regional Park is home to wildlife and cultural treasures. Unfortunately, years of neglect have left this park dilapidated and severely polluted. To return this park to its former glory, the M2O project was launched. In this landscaping project, the aim is to return Manzares River Park to its original state. Hence the name ''Madrid to its origins." The plan includes a multi-year plan to restore nature around the river combined with the renovation of Madrid's cultural treasures.
