The Hotel Astor on Times Square circa 1916. Note roof garden and, at lower right, the elaborate marquee for the film "Civilization." (George Grantham Bain Collection.) The building, at 1515 Broadway and West 44th Street, was demolished in 1967 and replaced by, in the words of one architecture critic, a "hideous tall office tower," 1 Astor Plaza, whose crownlike top is a familiar sight from across the Hudson River in New Jersey.
Cahokia, Illinois, United States Few Americans realize that we have the remains of a lost ancient civilization right here in the United States – in Illinois, just across the Mississippi River from St. Louis, Missouri. The Cahokia Mounds Historic Site is all that is left of an indigenous civilization of the Mississippian culture, settled around 600 CE.
