Although I was not very lucky, because it was cloudy, I did enjoy the panorama from the top platform a lot. If you can, you should climb the tower one hour before sunset, when the view is at its best.
In this photo you can see the 'Palais de Chaillot' in Trocadero. It was constructed in 1937 and houses several museums, among others the "Musee de la Marine" and the "Musee de l'homme".
