Had to scale the sizes down with this program for some reason so they aren't all super detailed but it's still a neat place
The two large walls with the reflecting pool in between represents the moment of time that passed from when life was normal and life was chaos. The truck McVeigh drove was parked on a street that was precisely where the reflecting pool is now.
The tree was completely undamaged in the bombing and is called the Survivors Tree because that's where everyone congregated that made it out alive.
The wall with handprints on it is the children's wall dedication to the victims and survivors.
The chairs are there for each of the victims and is in the place within the building they were supposed to be when the bomb went off.
