Located in the historic old railroad depot right on the banks of the Mississippi River, the LASM has several galleries of artwork (I sorta skipped through that part), a gallery of Egyptian artifacts including a mummy from Thebes (which alas did not allow photography), and a gallery of astronomical and earth science. Here are some photos.
