As usual during the Mercè festivities, Montjuïc Castle hosts contemporary circus arts from Mercè Arts de Carrer. Some 30 circus companies from around the world gather at the castle for three days to perform various techniques and disciplines. Companies from here as well as from Sweden, France, Argentina, Mexico and the United States will show off their stuff. The Montjuïc Castle Combined Circus has been coordinated and directed from Stockholm by director and choreographer Hans Marklund. Coming from Stockholm are Jan Unestam, Patrik Elmnert 5 & Toni Pezzo, and Anton Graaf & Einar Kling-Odencarnts. Catalan artists include Guillem Albà, Les Capgirades, José Luis Redondo, Irene Estradé and Sergio González.
The Ateneo Popular 9Barris bring a combo of six international and local companies of trapeze artists, jugglers, rope walkers and acrobats.
