Later, the second floor of the house briefly housed the National Club between 1892 and 1895, being owned by Ignacio de Osma y Ramírez de Arellano [es] through the Ramírez de Arellano y Baquíjano Testamentary. Starting in 1897, the house functioned as the first location of the International Bank of Peru, and was later occupied by the renowned Astoria restaurant during the 1920s.
After remaining for years in a state of natural deterioration over time, the house is currently preserved as a restored house museum and open to the public since 2008. For this, it was financed by the Chilean Army at the beginning, and later received contributions from the Chilean government through cultural funds from the Foreign Ministry through an agreement with the Pontifical Catholic University of Peru (PUCP).[1] Within its premises, it has a room adapted for exhibitions of historical-cultural interest.[2] It is administered by the PUCP's Riva-Agüero Institute.
