What to see in Lisbon in 2-3 days?

In 2-3 days, you’ll come across the major monuments of Lisbon: the Belém Tower and the Jerónimos Monastery, a UNESCO-listed site, tell the story of the great age of discoveries. Tram 28 climbs between the alleyways of Alfama, the cradle of fado. Between two visits, a pastel de nata is a must—perfect before checking out the route of the Lisbon Marathon.
