Last week, towards the end of the afternoon, we ran into, what I think, was a folk festival. We followed the crowd of participants into the district, intrigued. Even a local dog was interested in what was going on. As they walked, several sang songs and played music. Finally, they stopped, at what must have been the gathering point, and started playing and singing some more (see video below).
We ended the afternoon with coffee and an Alfama pastry.
