"There is something more powerful than each of us, a combination
of our efforts, a Great Chain of industry that unites us." - Andrew Ryan
- "Hey, hey… It's alright. I'm not like the rest… I'm a progressive!"
- ―Male Civilian[src]
The Lansdowne Residence is a building in Columbia, found in the Comstock Center Rooftops. By the time the player enters, there is only one occupant: an unarmed person who is philosophically a progressive.
Inside a bedroom upstairs, there is a locked Chest that starts an optional mission. Booker DeWitt must then find the key to unlock it. The key's location is on a podium inside the Fraternal Order of the Raven lodge. It is easily seen as it is in Booker's path to finding Elizabeth. The building itself says, AUDEMUS PATRIA NOSTRA DEFENDERE.
Inside the chest, one may find:
|Comstock Center Rooftops|
|Rooftops||The Blue Ribbon · Lansdowne Residence|
|Constitution Square||Montgomery Residence · Fraternal Order of the Raven|
|Clash in the Clouds||Raven's Dome|
