Key of Orthanc

The key or keys that granted entry to the otherwise impenetrable tower of Orthanc. They first enter history at the time of the Oath of Eorl, when that tower was sealed by the Gondorians, and the key taken to Minas Tirith. At the request of Saruman, Steward Beren later surrendered the key to him, and he took up his abode in the ancient Gondorian stronghold.
