In 1869 a post office was established under the name Norwood, a contraction of "North Woods."
The village was originally called Norwood, but in 1874 the name was changed to Glenmoore in recognition of the founder and the fact that it is in a narrow valley, or glen.
It was the birthplace of William Moore McClure, a Union Army colonel during the Civil War. According to DeLeon, Glenmoore is home of "... the smallest church in the world..." where the downtown is so small that it "... consists of an intersection with no traffic and one antiques shop next to a convenience store...."
The Glenmoore Historic District was listed on the National Register of Historic Places in 2011. It encompasses 56 contributing buildings.
