It’s a spacious leisure plaza at the Inner Harbour. During the years from the reign of Emperor Kangxi to Emperor Tongzhi in the Qing Dynasty, it functioned as a pier for the import of opium. It was also the first wharf reserved for opium trade and the first duty-levying area for tobacco taxation throughout the history of Macao and China, and even considered as the cradle of the Opium War. In the late 19th century, it was turned into a more spacious area due to land reclamation. The plaza became vibrant at night with stalls serving tea and entertaining performances in the past. It was also once a marketplace, where lots of venders gathered for business. Today, the plaza has become a recreational area for local citizens.
