At night, a structure is illuminated with green lights in Asenovgrad, Bulgaria. To the left, a brightly lit tower emits a strong vertical beam of light. Adjacent to the tower, illuminated rocks are situated at the top of a hill. To the right of the rocks, a path or road is visible, lined with more subtle lighting. The silhouette of a mountain range forms the backdrop. A tree with bare branches is silhouetted in the upper left of the frame, obscuring the sky.
