West of central Buenos Aires a vast, mostly residential area spreads out for over a dozen kilometres towards Avenida General Paz. Sights here are scattered; perhaps the neighbourhoods’ greatest appeal lies in their relative lack of tourists, offering a prize glimpse into the lives of ordinary working- and middle-class Porteños. Architecture fans shouldn’t miss the stunning Palacio de las Aguas Corrientes in the barrio of Balvanera, the neighbourhood just south of Recoleta. Northwest of Palermo, the barrio of Chacarita is best known for its namesake cemetery, where tango singer Carlos Gardel is buried. Caballito, right in the heart of the city, has an entertaining natural history museum. Finally, right at Buenos Aires’ fringes, the hugely enjoyable gaucho fair, the Feria de Mataderos, provides one of the best days out in the city.
