The Tagus River crosses Spain before reaching the sea and flows into the Atlantic Ocean. Approximately 15km links the Tagus and the port city of Lisbon. During the 21st century, the river banks were mainly linked to industrial activities, creating an important separation between the river and the rest of the city. Mostly because of the industrial decline, the Tagus river banks have been undergoing major rehabilitation through various urbanization projects for more than 20 years. The aim is to develop new leisure, cultural and tourist areas while developing new residential areas in some part it.
