It’s a day Americans will never forget – Sept. 11, 2001.

Nearly 3,000 people died in the attack, known as the deadliest in American history. Not only were lives forever altered, a new “terror” threat was established as hijacked planes crashed into the Twin Towers in Lower Manhattan, the Pentagon and into a field in Pennsylvania.

Thirteen years later, as memorial ceremonies are being held across the country, new life has arisen out of the ashes and continues to take shape. A new building stands where the towers fell in Manhattan. A museum dedicated to that day is now open to the public.

In our nation’s Capitol, President Obama, joined by his wife and Vice President Joseph R. Biden Jr., bowed their heads at 8:46 a.m. Thursday, the time the first plane struck the north tower.

A host of other memorial services and events are being held.  Here’s a recap of how we’re remembering 9-11 across our state and nation:

• Remembering Alabamians killed in 9-11
• Alabama mother honors her son
• New York City remembers
