"Jougs" were an instrument of punishment for ecclesiastical or criminal offenders. This iron collar was put around the neck of the offender, fastened with a padlock, and then attached by means of a chain to the church door or a nearby tree or post.
I saw this woman outside a small temple in the city of Patan. This is a fairly heavily cropped photo. Her small child was playing in what was originally the right side of the photo, but there was also the blurred head of somebody else in front of the baby, so I decided to delete that part.
