The Genesee County Courthouse is located at the intersection of Main and Ellicott streets in Batavia, New York, United States. It is a three-story Greek Revival limestone structure built in the 1840s.It replaced an older timber frame courthouse near the current site, which served what was at that time the entire Holland Purchase, the vast tract that is today Western New York. At the time the courthouse was built, the county had been reduced to its current size by the creation of 10 other counties from the purchase. Construction materials were all sourced locally.Later it underwent some minor renovations. While Genesee County has subsequently built additional court facilities nearby where most judicial activity takes place, it is still used for some court purposes as well as offices for the county manager, attorney and the meeting place of the county legislature. In 1973 it was listed on the National Register of Historic Places. Nine years later, in 1982, when the Genesee County Courthouse Historic District was added to the Register, the courthouse was again included as a contributing property.
