"There are two Barcelonas," said Alberto, a friend, as we cycled on the streets of Barcelona, "one on the east side of the Diagonal and one on its west." We were biking on the Avinguda Diagonal, which is Barcelona's broadest and arguably the most important street. Avinguda Diagonal cuts the city into two halves, diagonally, hence the name. The construction of the street started in 1859, till it came into its current form in the 1970s. I was intrigued by Alberto's comment on two Barcelonas, so I asked him to elaborate.
