The Old Mansion is a large manor built on the outskirts of Twilight Town. It is mysterious and derelict - rumor has it to be haunted, or at least is said in the Simulated Twilight Town. Its past is an enigma, but it plays a large role in the Realm of Nothingness.
After leaving The Woods, you arrive at The Old Mansion which is the name for the gate and the front courtyard. Upon entering the Foyer, the Mansion splits off into three different directions. If you go into the door on the left side of the Foyer, you enter the Dining Room. If you go up the left set of stairs and follow the walkway to the door, you reach the White Room. If you go up the right set of stairs and enter the other door, you reach the Library.
In the Library, there is a false floor that hides a staircase that goes downward which leads to a door. Through that door is the Computer Room where Ansem the Wise was able to monitor the Simulated Twilight Town. There is a machine that also sends Roxas and Riku into the Simulated Twilight Town. The doorway to the left of the computer leads to the Basement Hall which has the portal to The World That Never Was inside. The Basement Hall then leads to the Basement Corridor which is a hallway leads to the Pod Room
