The history of the city of Beihai is rooted in deep antiquity. Serving as a trading port and fishing hub, it has been known since the times of the Qin and Han dynasties. During the Tang Dynasty (618–907 AD), the city became one of the departure points of the famous Maritime Silk Road. An important milestone in its early history is the settlement of Bailong ("White Dragon"), established in 1374 and renowned as a centre for pearl harvesting for the imperial court. It is believed that Beihai received its current name, which translates as "North of the Sea," around 1662, during the early Qing Dynasty.
The key factors that determined Beihai's destiny as a vital coastal centre are closely linked to its geography and historical events. Its advantageous location on the coast of the Gulf of Tonkin in the South China Sea provided the city with a strategic advantage for the development of maritime trade. A turning point was the signing of the Chefoo Convention in 1876, under the terms of which Beihai was opened to foreign trade, transforming it into an international port. Following this, representatives from European nations began to actively settle in the city, building consulates, hospitals, and trading companies, contributing to rapid modernisation and economic growth.
The city's economic and cultural development went hand in hand with its transformation into an international port. Initially, Beihai's economy was built on maritime industries such as fishing and, in particular, the pearl trade. With its opening to foreigners, the city quickly turned into a bustling trading hub, and this fusion of cultures was reflected in its unique architecture. The most striking example is Beihai Old Street (Zhuhai Road), where "Qilou" or arcade buildings have been preserved to this day. Their style represents a blend of European and traditional Southern Chinese architecture, serving as a hallmark of the city and a testament to its rich history.
