Nick de Semlyen stated, in jest, that we may see Saruman apply for a building permit for Orthanc in the Rings Of Powers TV series. But it is my pedantic duty to inform him that Orthanc was built by the Númenóreans towards the end of the Second Age, and Saruman only came to Middle-earth 1,000 years after the Third Age had begun and was given the keys to Orthanc in 2759 of the Third Age.
