Correct Answer: Human pyramids
So why is this answer correct? : Each year on September 24, Barcelona, Spain, celebrates its biggest annual street festival: La Mercé. After Pope Pius IX declared La Mercé the patron saint of Barcelona in 1868, the city began to hold celebrations in her honor. The streets come alive with parades and castellers — street performers who make human pyramids up to nine levels tall.
