English: Cadastral map of Shameen [i.e. Shamian Island] in Canton [i.e. Guangzhou]. It is one mile in circumference and lies just off Canton, which has always been a center of commerce, competing with Hong Kong, only sixty miles away. Because the island was a British and French Concession, it was carefully patrolled and connected to the mainland on the northern side by the carefully-guarded "English Bridge" and a French Bridge on the eastern side. The larger western part was English and the eastern part French. Each had its own municipal offices, even its own police forces, Sikhs for the British, Annamites for the French. The map shows in detail the use of the offices and buildings on the island.
