Archangel Michael and sinners

Here is a roadside shrine I came across in the town of Ancora in northern Portugal. Behind bars is a painted and carved depiction of sinners amidst flames and above them the triumphant figure of the archangel in what I’m guessing is a vague idea of Roman dress though the cap is curious. These kinds of shrines can still be found all over Europe and would once have offered travelers a place to pray while en route. Many have rotted away, made of perishable materials, others would have been destroyed as idolatrous in Protestant Europe while some have survived.
