While the attacks happened at the Twin Towers in lower Manhattan, the Pentagon across the Potomac River from Washington and a lonely field outside Shanksville, Pennsylvania, the entire nation — and indeed the world — absorbed the horror of airliners being turned into weapons.
Demonstrating the enduring legacy of that day in 2001, here are some of the places holding observances around the United States on the 18th anniversary of 9/11:

The memorial and museum will be reopen the public at 3 p.m. Wednesday.
And public is invited to the Tribute in Light that will shine upward from the 9/11 Memorial Plaza, which will be open until midnight. The museum’s website says “the lights will be on beginning at sunset on September 11 and will fade away at dawn on September 12.”

Other observances include:
The visitor Center and viewing platform at the 9/11 memorial for Flight 93 near Shanksville, Pennsylvania.
