New York’s biggest museum street party is going online! Since 1978, the Museum Mile Festival turned Fifth Ave into an open-air celebration of art; this year, eight museums will hold free virtual events for the all-day party, tagging #VirtualMuseumMile on Twitter, Instagram and Facebook. The participants are The Africa Center, the Cooper Hewitt Smithsonian Design Museum, El Museo del Barrio, The Jewish Museum, The Metropolitan Museum of Art, the Museum of the City of New York, the Neue Galerie New York and the Solomon R. Guggenheim Museum. All ages.
