The striking blue and purple illumination of the unique Casa Batlló building at night.

The video opens with a low-angle shot of Casa Batlló at night, illuminated with blue and purple lights. Text overlays appear, introducing the event. We then see interior shots of the building, featuring architectural details, lighting effects, and people interacting with augmented reality on tablets. The final scenes show the exterior of Casa Batlló again, with a crowd gathered outside, and a call to action for tickets.
