Where is this chained man statue, photographed a century ago?

According to metadata, this image is claimed to be taken between 1880 and 1926 and the location is stated just as "Europe".

If the photographer is correctly identified, most of his photographs were taken in Catalonia and Spain and a few of them near the Alps.

I haven't been able to find the statue anywhere, neither with reverse image search nor by searching for sculpture groups with a chained man.

The image and metadata comes from here in Wikimedia Commons and it can also be found in its original location.

I'd like to identify the image in order to properly label it in Wikimedia Commons. Some background information is in a previous question about another image.
