http://cjonline.com/stories/030299/kan_courthouse.shtml The Chase County Courthouse in Cottonwood Falls can keep its designation as the oldest functioning courthouse in Kansas. But, contrary to a story in the Feb. 21 Topeka Capital-Journal and other claims, it isn't the oldest courthouse still in use west of the Mississippi River. Not by a long shot. Astute readers alerted The Capital-Journal that a story about the courthouse was inaccurate. There are several courthouses still being used this side of Old Man River that are older than the historic building in Chase County, which is now in its 126th year. ( Now skipping down through the story , there is, of course, mention of the Mariposa Courthouse- built 1854-) But that's not the most interesting part- if like me you have seen the claim that the Mariposa Court House is the "oldest Court House in continuos use west of the Mississippi" then this will interest you............ the article goes on to say: And the oldest still-functioning courthouse west of the Mississippi uncovered in The Capital-Journal's informal survey? The 156-year-old building located in VanBuren County in Keosaqua, Iowa.. ======================= Does anyone have Pinkerton and Radonovich's Mariposa Court House Book? Do they make the claim that Mariposa is the oldest Courthouse in continuous use in California, or West of the Mississippi? Thanks, Carolyn
