Time Out says
Like the Ajuntament, the Palau de la Generalitat has a Gothic side entrance that opens out on to C/Bisbe with a beautiful relief depicting St George (Sant Jordi), patron saint of Catalonia, made by Pere Johan in 1418. Inside the building, the finest features are the first-floor Pati de Tarongers (Orange Tree Patio), which was to become the model for many patios in Barcelona, and the magnificent chapel of Sant Jordi of 1432-34, the masterpiece of Catalan architect Marc Safont. The Generalitat is traditionally open to the public on Sant Jordi (St George's Day, 23 April), when its patios are spectacularly decorated with red roses, but queues are long. It normally also opens on 11 September (Catalan National Day) and 24 September (La Mercè). The guided tours are generally in Spanish or Catalan, so it's best to call ahead for an English-speaking guide.
