The Old Wanchai Post Office is located at the eastern junction of Wanchai Gorge Road and Queen's Avenue. It is the oldest existing post office building in Hong Kong. Founded between 1912 and 1913, it was officially opened to Wanchai Post Office in 1915. This simple pyramid top, curvilinear building, gables and gray sculptures are very distinctive. It is now used by the Environmental Protection Department as an environmental resource centre. In the interior, there are still special legacies such as counter, mailbox and stamp vending machine. On the wall, there are pictures of the old operation of Wanchai Post Office.
