(if you want a large panorama, it's here. You can count battlements on the castle and see tiles on roofs in the middle distance, but it is 7MB long)
Here's sunset, viewed from the Miradour da Gloria in the west. The castle is at the right-hand edge, the square right in front is the Praca dos Restauradores and the little patch of trees behind it is the Miradour da Graca on the other side of the city. Avenida Liberdade is the first set of trees above the railings, and on the far left you see some of the big modern buildings around Parque Eduardo VII.
