Barcelona is famed for its emblematic tourist spots, such as the Palau Güell and Park Güell. However, not many people are aware that many of the city’s famous tourist sites were actually built with fortunes made from its 19th-century slave trade.
In medieval times, it is estimated that 10 percent of the city’s population were slaves. Now, the Associació Conèixer Història exposes this dark secret by running guided tours to discover the traces left by the city’s slave trade. Starting near Plaça Catalunya, stopping points include some of Barcelona’s most iconic monuments and public spaces, such as the Antonio López statue and Plaça Sant Jaume.
“It’s an uncomfortable memory,” said historian Oriol López of the European Observatory of Memories. “It’s not taught in schools here and it’s still not something that those in positions of authority want to look at.” Priced at €15 per person, you can buy tickets for the two-hour tour here.
