More details in <a href="https://comma2026.vercel.app/workshops/">https://comma2026.vercel.app/workshops/</a>. <br>Finally, the 6th Summer School on Argumentation will take place immediately prior to COMMA, 9th - 13th September 2026 (details online at <a href="https://comma2026.vercel.app/ssa/">https://comma2026.vercel.app/ssa/</a>).<br><br>The different events of the conference will be held in two different venues, the Resid?ncia d'Investigadors (Carrer de l'Hospital, 64) and the CSIC Delegation in Catalonia (Carrer de les Egipciaques, 15), both in Ciutat Vella, in the city center of Barcelona, and just a short walk from each other. Specifically, they sit in El Raval, one of Barcelona's oldest and most characterful districts, on the western side of La Rambla, part of the city's medieval old town.
