The entrance to the Sanctuary are towering double doors exactly 180 feet high, displaying the Sanctuary logo in the centre, close to the top. The cogs and cranks beside it screech and groan when the doors open, which is rare to occur. Instead, there is a miniature door 10 feet high which opens for new survivors. Supplies, which rarely come now, are transported to the very back of the Sanctuary. However, if specific mutants wanted for interrogation or some other reason a caught, they are transported through the city, through the smaller doors for everyone to see. The walls on either side are impossible to climb, and guarded by many soldiers that are always on the lookout for threats. The dome, which covers the Sanctuary, begins at the top of a second wall behind the first.
