The museum occupies a Federal Empire Victorian brick mini-mansion. Every piece of furnishing in the home, dating from 1840 to 1900, has a Platte County history. The first level includes: a parlor; sitting room with bronze marble fireplace; dining room with large double sliding wood-on-wood German hand-grained doors; kitchen with a German tongue and grove wood ceiling; and latticed back porches. A curved staircase made of walnut and mahogany leads you to the second floor where there are four bedrooms. Another staircase connects the second floor and the kitchen. The basement, which once contained a cooking area, dining area, wine cellar, cistern room, wash area, and workroom, houses the Platte County Historical Society's genealogical library, archives and display rooms. The museum has a rare Civil War collection of Col. Charles E. Sinnet, a Union soldier. Open April 15-Oct. 15. Admission: $3; younger than 12, free.
