An internal view of a lit wood-burning stove or fireplace insert, located in Stoikite, Bulgaria. The dark gray metal-framed glass door on the left is ajar, held open by a dark metallic poker inserted into the door's handle mechanism. Inside the firebox, multiple wood logs are actively burning, producing bright orange and yellow flames. Ash and glowing embers are visible beneath the logs, resting on the dark internal grate. The back panel of the firebox features a geometric pattern. Below the firebox, a dark, possibly slate or stone, tiled hearth extends horizontally. A dark metal ventilation grate is visible at the very bottom center. A light-colored wall is partially visible in the upper left background. No individuals are visible.
