One of the most atmospheric neighborhoods in Lisbon, the Barrio Alto was the area that remained relatively unscathed from the 1755 earthquake. This barrio of tight winding alleys, cobble stone streets and beautifully decaying structures that make wandering around a pleasure with ample picture taking opportunities.
Sadly, it also contains most of the areas touristy restaurants, loud bars, rowdy trash and hen parties on weekends. For a brief period is was the epicenter of gay life in Lisbon but most of the bars [and gays] have moved on to the Principe Real. Currently the Barrio Alto is going through a bad case of "AirBNB-itis" [as iare many paces in Lisbon. The area is gentrifying rapidly and, occasionally, becomes a flash point for all the reasons long term Lisbonites dislike tourism.
It is one of the two barrios in Lisbon where traditional Portuguese music or fado can be found in abundance. While most experiences involve a pricey [and rather pedestrian] dinner and show, we managed to see an early performance at a well respected placed called Adega Machado. It was interesting, not really either of our styles and, thankfully, shorter than committing the entirety of an evening to.
Never the less, the Barrio Alto definitely a not miss part of the city that we find ourselves going back to day after day.
