PROMPT:
Create a breathtakingly realistic image of a majestic medieval castle situated on a lush emerald hill, surrounded by a serene turquoise lake, with a few sailboats drifting lazily on its surface. Incorporate vibrant colors, avoiding pink, to bring this fantastical scene to life. The castle's stone walls should glisten with a warm golden light, while the surrounding foliage is a mix of deep greens and blues. Include intricate architectural details, such as towering spires, grand archways, and ornate stone carvings. The atmosphere should exude a sense of tranquility and mystique, as if the castle holds secrets and stories of centuries past.
