The palace of Sheogorath the Madgod, from Oblivion:Shivering Isles. This took about a month to make, and many design revisions, so please favorite/diamond if you like it! :D

Features:

• Full courtyard
  
• Realistic Mania/Dementia gardens
  
• Sheogorath's Throne
  
• My attempts at representing those souvineer pedestals you get after each quest
  
• A rather small version of the fountainhead (Pools of Mania and Dementia)
  
• House of Mania (but no Halcyon Conservatory or Duke's Quarters. :( )
  
• House of Dementia (but no Private Gardens or Dutchesse's Quarters either)
  

Also, the texture pack I used in the images is Dokucraft, so it looks best in that pack, though any pack should do.
