Glen Historic District is a national historic district that includes 52 contributing buildings and two contributing sites. The district encompasses the historic core of a rural crossroads hamlet. The majority of the structures are 1.5 or 2-story, timber framed buildings with gable roofs. At the crossroads are the most distinguished buildings: two large Federal style residences, a mid-19th century general store and a distinguished Second Empire style brick residence built in 1878. It was listed on the National Register of Historic Places in 2001.
