Create a serene and mystical medieval garden with stone walls, adorned with ivy and moss, surrounded by a babbling brook. The space is illuminated by soft, warm candlelight and lanterns, casting a golden glow on weathered stone benches and intricately carved wooden trellises. Earthy tones of terracotta, sienna, and moss green dominate the palette, complemented by rich jewel-tones of emerald and amethyst. A lush carpet of wildflowers and herbs, including lavender and chamomile, spills over stone pathways, while towering cypress trees and ancient oaks provide shade and structure to the space. A rustic wooden gazebo, adorned with fresh greenery and flowers, stands at the garden's center, inviting contemplation and relaxation amidst the tranquil atmosphere.
