"Design a grand entrance gate for a public park inspired by the iconic Bab-e-Khyber in Peshawar. The gate should reflect the rich cultural heritage of Peshawar, incorporating traditional Islamic architectural elements like arches, intricate geometric patterns, and stone carvings. Use historical motifs and design cues such as floral engravings, calligraphy, and ornate detailing. The color palette should include earthy tones of stone, copper, and gold to represent the historical significance of Peshawar. Surround the gate with lush greenery and provide a sense of grandeur and welcoming into a cultural park."
