The first building to serve as the State Capitol was built in 1832 as the "Territorial Courthouse". The court house was on the corner of Griswold Street and State Street. This brick structure was one of Michigan's earliest Greek revival buildings, with a portico of Ionic columns and a central tower of 140 feet (42 m). Built at a cost of $24,500 ($ in ), the building housed the territorial government and state legislatures until 1848, when a hastily erected wood building was constructed in Lansing following a decision made March 17, 1847, to move the capital from Detroit to Lansing. The Detroit building then became a public school (the Union School, at one time the city's only high school) and library until it burned in 1893.
