Sunken ruins of an ancient Greek temple resting on the ocean floor. Marble columns are covered in colorful coral and sea anemones. Schools of tropical fish swim through the broken archways. Shafts of sunlight penetrate the deep blue water, illuminating the sand and the weathered stone statues. Bubbles rise from the ruins. Majestic, serene, underwater photography, highly detailed, 8k resolution, National Geographic style.
