In 2007, the Port of the Moon and roughly 1800 hectares of the surrounding urban area were listed a UNESCO World Heritage Site because of its outstanding and "innovative classical and neoclassical architectural trends" and Bordeaux's prominence as both the center of the historical wine industry and as a global trading center for more than 800 years.[2] The World Heritage Site is the largest urban area inscribed by UNESCO (as of 2021), covering roughly 40% of the entire city's area.
