10 Museums In Washington D.C. Every History Buff Should Visit
"This gallery was created by Andrew Mellon in 1937 when he offered up his own personal collection and finances to Franklin D. Roosevelt to build this place. There are two different buildings and a sculpture garden filled with some of the world's most treasured pieces of art that donors have given to the museum over the years. It is free to enter and any history buff with an appreciation for creative thinking will jump at the opportunity to visit."
