Today marks the 11th anniversary of the horrific 9/11 attacks.
67 British people were killed that day, along with hundreds of New York firefighters, the passengers on board the four hijacked airplanes and the thousands more who were in or around the World Trade Center.
It's one of those days that will continue to stick in our memories, for some more than others.
Thousands of people lost their loved ones and many people continue to suffer from illnesses linked to that fateful day.
Below are some images of the Twin Towers which defined the New York skyline from the time they were constructed, to the day they were destroyed.
US citizens will tell you they feel their nation is stronger having been brought together through those horrific events; security has been strengthened in nations all around the world; and many of those directly affected have found a way to overcome defeat and build successful lives, having been inspired by those they lost.
I'm sure it's a day we will continue to remember forever.
