White-clad crowd moves through Pamplona's cobblestone streets

A group of people in white shirts and red or blue accents are walking down a cobblestone street between tall buildings. Most of them are facing away from the camera and moving towards the right of the frame. Several individuals are carrying a large purple flag with an emblem on it. One person in the foreground is carrying a blue bucket on their shoulder. The buildings appear to be old European architecture with balconies and windows. The sky is visible at the top of the frame and appears partly cloudy. The overall atmosphere seems to be festive, possibly a parade or procession.
