The Bronze Statue Head is the hundred and first treasure that can be found in Uncharted 2: Among Thieves.
The Bronze Statue Head is found in Chapter 25 - Broken Paradise. Unless you're a completionist, you don't really need a 101st treasure when there's no trophy attached to it, but nonetheless, we'll tell you precisely where it is. From the location of the Wooden Mask you just found, continue to run up the stairs before you. There are no enemies here, so you can keep running up, up, up. When you reach the floor with a huge split in the ground, you're in the right area to get this treasure. Look along the far wall, near some debris, and you can easily acquire this final treasure not only of the chapter, but of the game at large. Congratulations!
