| The Tagus valley is narrow, and barren of supplies, and almost as circuitous a route from France as the Guadiana. |
| The castle's impressive battlements and tree-shaded gardens offer excellent views over the city and the estuary of the Tagus river. |
| The same is true of the catchment areas of the rivers Guadalquivir, Guadiana and Júcar, Tagus and Douro. |
| Moreover, the point of discharge is situated outside the outer limit of the Tagus estuary. |
| Suddenly the entire structure, built on the unconsolidated sediments of the Tagus RAver estuary, sank into the sea, as if swallowed up by the devil himself. |
| The Tagus covers the heart of Portugal and Spain and has been of vital importance to the modern economic development of the two nations. |
