This is the classic sunrise scenery along the Douro River in Porto, Portugal. Mist shrouds the calm river surface, three traditional Rabelo boats that once transported Port wine are moored quietly. The iconic Dom Luís I Iron Bridge spans the sky on the right, old town residences with orange-red roofs scatter on the opposite bank. Warm orange sunrise glow spreads across the sky, creating a soft lazy atmosphere. The Douro River flows through Portugal's famous wine region, and the Porto old town along the bank is a listed World Cultural Heritage site.
