This is by far the most interesting place in the city. If you can only do one area, I would recommend you do this. Highlights include: • the best views of the city • the Mourish castle of Saint George (11th century), SE Cathedral (oldest cathedral in town 12th century) and the ruins of the Roman Theater (1st century) • Fado - traditional Portuguese music (although you can hear this in other places as well, this is where the most authentic Fado houses are, from 7pm onwards) • Ginginha (Portuguese sour cherry licor) tasting
