The most significant areas of the finished part are: The first stage of the project “the Linear Park on the River Manzanares” by Ricardo Bofill Taller de Arquitectura was completed in 2003.

The geographical location of the park, south of Madrid, is crucial to the city, which is spreading progressively towards the Meseta and needs open ground to break the urban tissue and to provide citizens with contact with nature.

The ambition of the project was to transform an area containing the capital's sanitation and electricity supply infrastructures into a major park that will also meet the recreational and sporting needs of the surrounding districts.

The previous studies on the treatment of the river that begun as part of Madrid's sanitation plan were followed by Bofill's design project.

The project foresees covering the sewer exits at the northern end of the park and isolating the water purifiers and electricity plant to hide the installations from view and mask possible emanating smells.
