At the end of the War of the Pacific, the Treaty of Ancon was signed in 1883 between Chile and Peru. Part of the understanding was a referendum would decide which country would own the towns of Tacna (now southern Peru) and Arica (now northern Chile) within ten years. During this period, the Peruvian consulate had their offices, a restaurant and their residence in the House Yanulaque, owned by a wealthy advocate of their views. After the Treaty of Lima resolved the debate, this house became the property of the Peruvian Ministry of Foreign Affairs.
