In short: The Port de la Lune, or Port of the Moon, is more than just a harbor in Bordeaux. Named for the distinctive crescent shape of the river winding through the city, this iconic landmark has defined the urban identity for centuries, appearing on everything from municipal coats of arms to modern logos.

The name Port de la Lune traces its origins back to the Middle Ages, derived directly from the sweeping, moon-like curve of the river as it bisects the city. This geographical feature became so central to the local identity that it was immortalized on the city’s coat of arms as a single crescent. Today, the municipality continues this tradition, featuring three interlaced crescents in its official logotype, signaling a deep connection to the city's historical maritime roots.

In 2007, UNESCO recognized the Port of the Moon and approximately 1800 hectares of the surrounding urban landscape as a World Heritage Site. This designation was granted in recognition of the city's innovative classical and neoclassical architecture, as well as its historical significance as a global trading hub and the epicenter of the wine industry for over 800 years. As of 2021, it remains the largest urban area ever inscribed by UNESCO, encompassing roughly 40% of the entire city.

Beyond its historical architecture, UNESCO praised the city for its modern commitment to urban renewal. The municipality has invested heavily in restoring and embellishing the historic quays and facades that define the city center. Notable landmarks included in these preservation efforts are the grand Place de la Bourse, the reflective Miroir d'eau, and the majestic Grand-Théâtre. These projects ensure that the Port of the Moon remains a living, breathing testament to centuries of trade and architectural evolution rather than a static museum piece.
