Listed on both the Kansas and National Registers of Historic Places , the building which houses the Museum was built in 1920 as a lasting monument to soldiers in World Was I, a gift from citizens of the city. The Memorial Auditorium was built as one of the finest buildings of its kind in Kansas, with a banquet room, kitchen in the basement, a stage and seating capacity of 1200 in the auditorium. The auditorium is still being used for many community activities, including our Travelogue film series.

The Museum depicts the history of Brown County which was settled in 1854. All the exhibited items have been donated by the people from Brown County. A Library houses genealogy research, old maps, Brown county records, Church records, school records, photographs, newspapers and old books. The Ewing Herbert Memorial Room was set up and donated by Dolores Herbert Hohnbaum. The Herbert's newspaper history dates from 1885 to 1977.
