This vertical video captures a dynamic urban sky at either sunrise or sunset, specifically in Barcelona, Spain. The shot pans slowly downwards, revealing the tops of buildings. Initially, the upper sky is a light, partly cloudy blue, transitioning to a dense layer of grey clouds below, which are illuminated with striking patches of bright pink. These pink hues intensify and spread across the lower cloud layers as the video progresses. On the right side of the frame, a distinctive, ornate stone tower or spire with Gothic/Modernista architectural elements is visible, featuring multiple pinnacles and a small cross at its peak. On the left, the top floors and cornices of a more conventional multi-story building, with balconies and windows, are seen. The cloud movement is subtle but noticeable, contributing to the evolving color palette of the sky. No people or visible text are present. The scene conveys a serene yet vibrant atmosphere due to the dramatic sky colors.
