This is the blue hour scenery of Peniscola, a famous coastal landmark in Valencia, Spain. The medieval ancient town sits on a sea-facing rocky headland, with old stone fortification walls surrounding scattered white residential buildings. The hilltop castle is illuminated by warm lights, and street lamps along the town give off soft warm yellow glow. Beneath is the tranquil deep blue Mediterranean sea, under the clear purple-blue night sky. Peniscola is also known as Gibraltar of the Mediterranean, a well-known historical tourist resort.
