Mount Cadon
From Tardis Wiki, the free Doctor Who reference
Mount Cadon was a mountain in southern Gallifrey, tall enough to reach to the transduction barrier. The Prydonian Academy was located at the base of Mount Cadon, and the House of Lungabaroow (given the name of the river Cadonflow) apparently near it. (NA: Lungbarrow) In his youth, the Doctor used to climb it while he was young. The Hermit used to tell stories to the young Gallifreyans, like the Doctor, on Mount Cadon. (NA: Lucifer Rising)
