The “People Tower” is constructed of 3024 stainless steel figures – all interconnecting together to form a 175-foot tower. It is a building made of people.
As visitors approach the “People Tower”, visitors will begin to hear the sound of a human heartbeat emanating from high up and deep within the center of the tower. This is the Heartbeat of Humanity. It is this sound that connects us all together and reminds us that we are all the same. As they gaze into the structural labyrinth of male and female figures and listen to the deep, resonating sound of the human heartbeat coming from within, it will be natural for visitors to lay their hands upon these symbolic figures in remembrance and prayer.

This is, to me, the best 911 monument I’ve seen or heard. This must be built.
