The House of Lungbarrow was one of the Prydonian Houses and the family home of the Doctor. It was located in the southern mountain range on Gallifrey, overlooking the Cadonflood River. The Doctor returned there in his seventh incarnation.
The Doctor's father once laid out all his plans and projects on the table in the Great Hall of Lungbarrow. He and Mr Saldaamir were interrupted when the First Doctor let a cobblemouse loose, which ran across the table and scattered all the plans and projects in the air. (PROSE: Unnatural History)
