I was looking through a back issue of The New Yorker yesterday evening and learned that the Barnes Foundation (Impressionist Art) had moved from its year-long location in Merion, Pennsylvania, into the city of Philadelphia. You can read an excerpt of the article here without a digital archive subscription or the full article if you are a subscriber.
Fortunately, there are also many pages and videos about the Foundation's collection on the web.
I really like this video from WHYY but, unfortunately, it can't be embedded. Please take a look even though it's not embedded.
Here's the Wiki entry for Albert C. Barnes. the man who put this wonderful collection together.
I love the design of the museum itself, designed to be as close to the original Foundation's home for the art as possible.
YouTube has many videos directly from the Barnes Foundation here.
