The "Little White School House" is, indeed, where the Republican Party was "born" back in 1854. There is a slightly larger home behind it, the Lyman House - which, for the longest time, was known as The Republican House Restaurant. My grandmother had her wedding reception dinner there. AFAIK it is no longer open as a restaurant or reception hall.
There is a BMO Harris bank with a drive-thru just to the south of the property, with a suitably large parking lot that is connected to another parking lot for the local Catholic church - which is where my Uncle Ralph's funeral was held.
I have mixed feelings about the place. There is history behind the house - a little school house built for the small town of Ripon, yes, but where a bunch of community and state officials met in protest (ironically) over the Kansas-Nebraska Act. They chose to splinter away from the Democrats, Whigs, and Free Soil parties to form the Republican Party.
@Dave can tell you more about the wonderful results of the Kansas-Nebraska Act, but to these people, it was the last straw. The question of slavery would be determined at the state level -
oh, the irony of state's rights being the reason why the GOP began in the first place! - which meant that any state could be a slave state if enough people
came into the state and forced the legislature to allow slavery "wanted" it to be one. Basically revoking the Missouri compromise and setting the nation toward Civil War.
I would be willing to bet that someone - which side, I don't know - wants to use the place as a rallying cry for protest.
EDIT: Or, of course, burn the place down.
