The French Concession was a foreign-controlled area in Shanghai, China, established in the mid-19th century. It was created after the Treaty of Nanking in 1842, allowing the French to govern the area independently. This district became known for its tree-lined streets, European-style architecture, and vibrant cultural scene. During the early 20th century, the French Concession attracted many expatriates and artists, contributing to its cosmopolitan atmosphere. It was a hub for commerce and social life, with cafes, shops, and galleries. The area remains a popular destination today, reflecting its rich history and cultural heritage.
