Centreville is in St. Joseph County, and in the West-Southwest Region. This community is located east of Three Rivers on State Hwy 86.
Centreville was named because of its location in the exact center of the county. Thomas W. Langley was the first pioneer to settle here, arriving in 1831, he built a tavern. That same year, the town was organized as the county seat. It later incorporated as a village in 1837. Today, the stately Victorian style courthouse still graces the center square of town, surrounded by small shops and businesses. This is also the starting point for visitors who come to see the Langley Covered Bridge, erected in 1887 in honor of the town father.
