Now that Booker DeWitt finally reached the Monument Island, he just have to find his way inside the tower if he wants to find Elizabeth and rescue her.
Even if the BioShock Infinite collectables in this chapter are relatively easy to find, those who dont want to search every room should use the BioShock Infinite collectibles guide below in correlation with the screenshots found at the end of the page.
You begin the chapter in a garden, and the path is blocked by a locked gate. Jump over the gate using your sky-hook and enter the building.
When you are in front of the angel statue, turn left. You should see the first BioShock Infinite Monument Tower Voxophone inside the locker that is opened.
TIGER BY THE TAIL; Ty Bradley; April the 8th, 1912
After you exit the first room with a lot of electric activity (where the three levers are), your objective points forward.
Instead of following it, head inside the room to your left in order to find the second BioShock Infinite Voxophone in Monument Tower, on the table near the sink.

Next, get through the door to reach another room with a lot of electricity (the Siphon room). As you enter the area, check the desk right in front of you, next to the blackboard.
The third BioShock Infinite Voxophone in Monument Tower is on top of the desk.
A REWARD, DEFERRED; Zachary Hale Comstock; July the 5th, 1912
Follow the rooms in which you observe Elizabeth, and when you reach the third one (after she opens a Tear to Paris), grab the fourth BioShock Infinite Voxophone in Monument Tower from the chair thats in the observation room (right next to you).
THE SOURCE OF HER POWER; Rosalind Lutece; September the 5th, 1909
