close-up of an architectural detail of a building in Strelna, Russia

close-up of an architectural detail of a building in Strelna, Russia. The central focus is a mosaic depicting the face of Jesus Christ, with a halo around his head. To the left and right of the mosaic are Cyrillic letters. Above the mosaic, on the apex of the building's facade, is a dark-colored, ornate cross. The facade itself is made of textured, reddish-brown stone, with decorative gold trim along the edge of the arched roofline. A small, green-lit lamp is affixed below the mosaic. The sky in the background is a pale blue with some wispy clouds. The architectural style suggests a religious building, possibly a church or chapel.
