September 24 will be a big day for anyone who's a fan of art, culture and history—and a treat for anyone who hasn't been inside a museum for a while (or ever).
As part of the 12th annual Smithsonian Magazine's Museum Day Live!, cultural institutions across the country open their doors for free to anyone (plus a guest) who goes online to pick a museum and download a ticket. Among those participating will be The Smithsonian Institution's long-awaited opening of National Museum of African American History and Culture in Washington, D.C.
"Twelve years ago, only about 200 museums participated in the event and now over 1,200 museums take part," Amy Wilkins, Smithsonian Media's chief revenue officer told CNBC.
"The Smithsonian is committed to making knowledge accessible to everyone and Museum Day Live! is an opportunity for museums across the country and their diverse communities to unite around that commitment."
