In Lisbon, there are plenty of things to see and do. Again, it will be your option. In the Belem neighborhood, there's the Monastery of Jerónimos (a masterpiece from the XVI century), the Standard of Discoveries, and the view to the river Tejo. In the city center, you can walk by Augusta street and Rossio Square or go to the top of the Triumph Arch in Commercium square. There are also the typical old neighborhoods of Bairro Alto or Alfama (with the Cathedral, Saint Anthony Church and the amazing viewpoint of Portas do Sol), where Fado music came from. Of course, we can also visit the Oceanarium in the new Lisbon.
