The exterior of Mayfield Psychiatric Hospital was seen briefly near the end of the season 5 finale Both Sides Now. Dr. Gregory House became a patient following his realization that the night he had spent with Lisa Cuddy as well as his detoxing from Vicodin were all hallucinations, causing House to also discover that he was suffering from psychosis. One of the Wards in Mayfield is Ward 6, a ward for patients that aren't a danger to themselves or others. This is the ward that House was placed in following his detox. Mayfield Psychiatric Hospital was a major location during Season 6.
