Svetulka (Bulgarian: Светулка) (Turkish: Çandır) is a village in Ardino Municipality, Kardzhali Province, southern-central Bulgaria.

[1] Momini Gardi, a peak close to the village, offers a scenic view for locals and tourists.

Built in the 1500s, it was constructed on top of a former Roman bridge that was part of an ancient route connecting the Aegean Sea and Thracian lands.

The site, used from the late Bronze Age, dates back to the 4th and 6th centuries BC and includes a large rock with about 90 carved niches where artifacts related to death rituals were placed.

This fortress is characterized by its unusual circular design, spanning 67 meters in diameter, and built from stones without mortar, covering about 0.5 acres.
