The Bronze Gates of Imgur-Enlil (or the Balawat Gates) were a set of wooden gates covered with thirteen bronze bands and decorated in Salmanazar III's war compaign scenes. They were discovered in 1876 in the ruins of the ancient Assyrian town of Imgur-Enlil (modern Iraqi town of Balawat) and brought to the British Museum, where they were displayed near the Eight Shedus.
In 1930, Indiana Jones used a visitor's tour of the British Museum to gain entrance into the Museum in order to reclaim Baldur's Ring from Dr. Theresa Lawrence's office. During the tour, the docent was describing the bronze gates when Jones slipped away and hid on top of a giant Shedu statue.
