For many, the Twin Towers of the World Trade Centre were an essential part of the New York skyline.
That emptiness is now commemorated in the 9/11 Memorial that opened recently at Ground Zero.
The actual footprints of the towers themselves have been turned into reflecting pools featuring the largest man-made waterfalls in North America.
In the centre of each pool, there is what seems to be a dark bottomless pit:
Those deep holes made me strangely emotional.
Perhaps because they seem to signify the emptiness and futility of lives lost, of love wasted and of senseless hatred.
Near the pools, you can see the new Freedom Tower rising up into the sky.
My hope is that the new memorial will celebrate hope and light.
Darkness cannot drive out darkness; only light can do that. Hate cannot drive out hate; only love can do that.
— Martin Luther King
