Topic sites to see in lisbon

I assume you have a good guide book? Two days isn’t very much time for Lisbon but among my highlights are Belem where the explorers left Portugal to make their discoveries in the world. A big must see there, make reservations in advance, is the Jeronimos Monastery. The nearby Coach Museum is interesting.
Explore Lisbon’s neighborhoods of Baixa, Chiado, Barrio Alto( take the elevador up) and Alfama. You will see beautiful blue and white tile covered walls as you walk. Visit the Tile Museum, unique to Lisbon. As you walk, look down at the tile designs.
Wherever you are buy Pasteis de Nata, the custard filled tarts that Lisbon is famous for, worth the trip there to eat one!
Ask the editors to correct your title from topic to top.

And add on the castle..great views... also a nice walk to the many viewpoints...One very pretty one is Sao Pedro de Alcantera. A fun activity is to ride the tram 28 or the vehicular teams.
