Immortalized in film and song, Fifth Ave first developed its high-class reputation in the early 20th century, when it was known for its 'country' air and open spaces. The series of mansions called Millionaire's Row extended right up to 130th St, though most of those above 59th St faced subsequent demolition or conversion to the cultural institutions now constituting Museum Mile. Despite a proliferation of ubiquitous chains, the avenue's Midtown stretch still glitters with upmarket establishments, among them Tiffany & Co.
New York home of President Donald Trump and family, the dark-glassed Trump Tower, at Fifth Ave and 56th St, has become a sight in and of itself and a popular spot for protestors. Security around the building is extremely tight and traffic slow.
