 The delegation was composed of 19 royal carriages and 22 corresponding to the grandees of Spain.The Catalan anarchist Mateu Morral, inspired by the anarchist movement in Spain, threw a homemade bomb, disguised in a bouquet of flowers, from the top floor of the building at Calle Mayor number 84, where the popular tavern Casa Ciriaco is located.The bomb was directed against the carriage carrying the royal couple but bounced off and ended up exploding into the crowd.
