The Museu do Fado in the Alfama is the definitive introduction to Portugal's most distinctive art form. The permanent exhibition traces fado from its origins as rough urban music in the Mouraria and Alfama neighbourhoods to its current status as a UNESCO Intangible Cultural Heritage. Interactive listening stations let you hear the key recordings; displays cover the instruments (the Portuguese guitarra and the viola baixo) and the great fadistas.
The building is in the heart of the Alfama, a few blocks from the Tagus waterfront. There is a good live fado programme in the evenings — check the museum's schedule for concerts. The museum itself is free on Sundays before 2pm; otherwise a modest entry fee applies.
