Casselton Commercial Historic District

Casselton Commercial Historic District is a 9.3 acre historic district in Casselton, North Dakota that was listed on the National Register of Historic Places in 1982.

The listing included 16 contributing buildings which historically included a department store, a financial institution, a Masonic meeting hall and other businesses.

The Masonic Block, at 31 Sixth Avenue North was built in 1887 in two parts, the first being a 50x90 ft part with four brick pilasters and a pressed metal cornice. The center of the cornice contains the words "MASONIC BLOCK", the date "1887" and a Masonic emblem. A second 50x90 ft part was built adjacent, with identical cornice and finial. In 2013, no Masonic lodges were known to be scheduled to meet in the building.
