Catalan referendum: Clashes as voters defy Madrid
National Spanish riot police arrived at another polling station nearby in Barcelona but again, people there kept them back.
One witness said there were scuffles and showed me a photo of a middle-aged woman with a bloody face.
But inside the school sports hall, there is a mood of celebration as people take selfies as they cast their votes.
Catalonia's former President, Artur Más - the man in charge when Catalan nationalists really started pushing for a referendum - told me that people were voting peacefully in the face of "a violent Spanish state".
