This turn-of-the-century property just beyond the Quai du 4 Septembre, Boulogne-Billancourt, is a wonderland of English, French and Japanese garden styles, terraces, a prarieland, rocky terrain, a rose garden and conifer wood. It was begun in 1893 by French millionaire/banker/philanthropist/idealist/internationalist Albert Kahn. In 1909, believing he could promote cross-cultural peace and understanding, he sent photographers and cameramen in 50 countries to take pictures of daily life. The adjoining museum has preserved the first collection in the world of 72,000 autochromes and 180,000 meters of films. The displays are rare and beautiful. Some of the subjects include the earliest known color photos of Vietnam, Brazil, Norway and parts of the United States. A small admission is charged, worth going to especially in spring and fall. Closed on Mondays, opens at 11 a.m., metro Porte d-Auteuil, bus 52 and 72
