Marsh Fritillary (Euphydryas aurinia)

Observation - Marsh Fritillary (Euphydryas aurinia). Description: This butterfly was seen on a sunny morning on the edge of grassland in the village of Hotnitsa in Bulgaria. I believe it to be a Fritillary of some sort. I wonder if there is anyone who can help with a more positive ID.
