This river is important for the country's history, serving as a vital trade route since ancient times. The scenic waterfront of Lisbon along the Tagus is lined with key landmarks, including the Belém Tower and the Jerónimos Monastery. The Tagus plays a significant role in the city's economy, providing opportunities for fishing, tourism, and recreation.
