Pierre,South Dakota is the only example of a state and capital in the U.S. that don't share any letters.
Exploration of this area began in 1743 when Louis-Joseph and François Verendrye came from France in search of a route to the Pacific.
South Dakota hired Bell & Detweiler Architects of Minneapolis, Minnesota and selected their design for the Montana State Capitol to use again for the South Dakota State Capitol with some variations, rather than asking the architects for an original design.
