Jenne Block
Jenne Block is a two-story brick commercial building in downtown Douglas, Wyoming. It is described as the most ornate commercial building in Douglas, with extensive terra cotta detailing. It was built for rancher and businessman Jacob Jenne by contractor Edward A. Reavill in 1916. The building housed a bank and the local "Douglas Enterprise" newspaper, as well as professional offices. Description. The rectangular building measures long by wide. The corner entrance is set at an angle to face the intersection of Center and South Third Streets and is topped by a terra cotta crest with a JJ  monogram. A raised entry at the middle of the long side provides access to the upper floors, with a basement stair set underneath. The elevations that do not face the street are blank expanses of brick. Jenne Block was listed on the National Register of Historic Places on January 6, 1998. See also. Morton Mansion (Douglas, Wyoming), built for Jacob Jenne's brother John (Jenne) Morton in Douglas
