Four North Shore communities will pause Friday, Sept. 11, to mark 25 years since the Sept. 11, 2001, terrorist attacks, with tributes planned in Glencoe, Northfield, Winnetka and Wilmette, according to The Record North Shore.

Glencoe's ceremony begins earliest. A memorial service starts at 7:46 a.m. at the flagpole at the corner of Vernon and Lincoln avenues, outside Am Shalom of Glencoe, 840 Vernon Ave. The time corresponds to the moment the first plane struck the World Trade Center's north tower, 8:46 a.m. Eastern time. The Village of Glencoe says the service is open to all.

In Northfield, a remembrance ceremony begins at 8:30 a.m. at the Fire-Rescue Facility, 1800 Winnetka Road. A brief speech will be followed by the tolling of the station bell to mark the moment the first tower fell.

Winnetka's tribute is visual rather than ceremonial. American flags will be planted across the Village Green on Thursday, Sept. 10, and left through Friday to honor the 2,977 people killed in New York, Washington, D.C., and Pennsylvania.

No formal ceremony is planned.

At Loyola Academy in Wilmette, the student council will again place American flags near the school's marquee sign at Lake and Laramie avenues. The annual display honors victims of the attacks, including Michael Lunden, a 1982 Loyola graduate who died at the World Trade Center.
