A process of a legal cleaning up began between 1875 and 1891 because of a complaint from a resident of the city, aboutmisappropriation of the town council lands located on the banks of Rimac River. In 1876, the “Sociedad de Fomento del Peru”(Society for the Promotion of Peru), owned by Enrique Meiggs was allocated with some lands that were occupied by the ancientwall of Lima, from Martinete to the plaza del Cercado (downtown Square), corresponding to the 3rd Section. This event createda real estate business and interests in buying lands of this area, but the activity continued in spite of the interruption causedby the Pacific War. In 1890, The interest of the Railway Company in buying these lands caused that the urban renewal worksbeing done ,continued their improvement process with the support of a private enterprise, in exchange of this the town councilwould give some of their lands located on the left bank of Rimac River.
