The city was given the face we know today at a specific period in time, and that was the years starting from the Gilded Age and the roaring 20s to the 1930s. Skyscrapers went up, public buildings were built, and grand avenues, such as 5th Avenue, were created. At the end of the 19th century, before the arrival of international brands setting up their flagship stores, 5th Avenue was where the wealthy chose to build their mansions. Important families such as the Vanderbilts, the Astors and the Carnegies all established themselves along this street, and used their considerable influence to keep it chic and polished (for example, by preventing bus lines running along its length). Many of those mansions can still be seen today, and 5th Avenue has remained in popular culture as an address for the very affluent, going as far as having a good chunk of it (the bit bordering Central Park) be nicknamed Millionaire’s Row.
