The city is dominated by the domed Capitol, which rises from a bluff overlooking the Missouri River to the north; Lewis and Clark passed the bluff on their historic expedition upriver before Europeans established any settlement there.
Jefferson City is home to Lincoln University, a historically black college founded in 1866 and later designated as a land-grant university.
In 2013, Jefferson City was named America's "Most Beautiful Small Town" by Rand McNally.
