I was delightfully surprised by this piece on the world's oldest museum built by a Babylonian princess 2500 years ago and excavated by British archaeologist Leonard Woolley in 1925. I remember reading this story in one of my first books on archaeology when I was 8 or 9 years old and hadn't heard it since. The whole article is very well done with a bonus picture of Woolley with his younger colleague, T.E. Lawrence.
