Thursday weekly market Activity · Granollers, Vallès Oriental, Barcelona Image of Granollers, not of the place itself. Instituted in 1040, it made the town the commercial centre of the Vallès, between the old Via Augusta and the road from Barcelona to Vic. It is still held on Thursdays around the Porxada, with stalls of fruit, vegetables, cured meats and farm produce. Photo: ca:user:amadalvarez (CC BY-SA 3.0) What to see and do in Granollers
