The Morgan County courthouse, completed in 1859, still shines in its red brick and Italianate design. This is one of very few pre Civil-War courthouses existing in Indiana. Built by Perry Magnus Blankenship. Architect Isaac Hodgson designed the courthouse. Mr. Hodgson designed six Indiana courthouses including Jennings County (1859), Morgan County (1857), Henry County, Bartholomew County (1871), and his largest in Marion County, in Indianapolis.
In 1899 Eugene Shireman, a Martinsville entrepreneur, turned his swamp land into fisheries and started Grassyfork Fisheries. Once dubbed the “Goldfish Capital of the World,” today Martinsville has several large fisheries that sell fish to many parts of the world. Shireman's actions transformed the landscape of the Martinsville area forever, and his fisheries can be seen today throughout Shireman subdivision. Martinsville is also home to other fisheries.
