The current structure is the third courthouse to have been built for the county. The original courthouse, built in 1807, was a small structure made of stone.James P. Bailey, who was responsible for the construction of Old Main at Geneva College became the architect of the new courthouse after the second one was destroyed by a fire in 1883. It was built in 1885, and is a three-story, brick and sandstone building in an interpretation of the High Victorian Gothic style. It features a large central, four-faced clock tower with two double pyramid shaped roofs.
Bailey's courthouse still stands today, and is currently the tallest structure in downtown Butler. The facility includes a Westinghouse elevator installed in the late 50s early 60s, several stained glass windows, a grand staircase connecting the first and second floors. The first and second floors are more designed to be gothic and art deco with several crown moldings, domed ceilings, marble floors and walls, and woodwork as well. The upper two floors have been made into offices and courtrooms. In the early 1990s a new government annex building was constructed beside the courthouse. The two structures are connected via skywalk. The annex building is 5 stories and consists of 2 basement levels, making a total of 7 floors. All 7 levels house offices and courtrooms.
