Sullivan County

Sullivan County is an administrative county in western Indiana with the Wabash River forming its western boundary. Numerous creeks and waterways run through the land, shaping the natural landscape of the entire region.

The county was created on December 30, 1816, from parts of Knox County, making it one of the earliest administrative divisions formed after Indiana joined the United States. This early establishment shaped how the western territories were organized.

The Sullivan County Historical Museum displays local objects and documents that help visitors understand how the region developed over time. Walking through the exhibits gives a sense of how people here lived and what mattered to them across different eras.

The county courthouse at 100 Courthouse Square handles all administrative services including property records and government operations. Visitors can go there to access public documents or ask questions about land records and official matters.

Sullivan County Park contains a sizable reservoir that serves double duty as both a water supply and a recreational spot for fishing and boating. This body of water is often overlooked by travelers but offers quiet places to spend time outdoors.
