Norwich — Norwich has had a long history of mixed emotions regarding infamous native son Benedict Arnold — whether to honor his heroism in the early years of the American Revolution or to join the rest of the nation in vilifying him as the nation’s biggest traitor.

On Monday, the Norwich Historical Society will host an unusual ceremony to mark the anniversary of Arnold’s birth on Jan. 14, 1741.

“Lights out for Benedict Arnold” will be held at 6 p.m. Monday in the plaza outside City Hall at 100 Broadway. During the 10-minute ceremony and program, speakers will address Arnold’s legacy and then the holiday lights at City Hall and the tree in the plaza will be put out until next holiday season.

Following the brief program, participants will head to Billy Wilson’s Ageing Still at nearby 57 Broadway for birthday cake.

The event is free and open to the public.
