Today?s Missouri Governor?s Mansion is the third of the series of buildings intended for the purpose that was ever constructed. The first two either burned down or just dismissed. This one was built in 1871 after the second mansion was damaged by fire and became the location of Thomas Reynolds? suicide in 1844.
Designed by George Ingham Barnett, the Missouri Governor?s Mansion that people know today is of the Second Empire architectural style. It is a three-story red brick building with mansard roof and four pink granite columns. It features a Grand Stairway that was carved of walnut.

It was restored and renovated a couple of times, under the administration of various governors. The most recent project aimed to bring the building back to its 1871 glory, and added antiques to its furnishings.

Public tours of the Missouri Governor?s Mansion are available, upon reservation.
