Marion Center is a borough in Indiana County, Pennsylvania, United States.

In 1885, New York banker Adrien Iselin purchased the Buffalo, Rochester, and Pittsburgh Railway.

[4] Marion Center had a vibrant community life in the late 19th and early 20th centuries.

Hotel Marion, built in 1879 by Alexander Adams, had 15 rooms and was three stories tall.

The second hotel, Mahoning House, at the corner of Main and Manor Streets, occupied the site of the former general store operated by McLaughlin, Kinter, and Company.

Passing the superintendent's exam upon completion of the program licensed one to teach in the county's common schools.

The first school in Marion Center, a log building on North Manor Street, burned in 1834.

According to the United States Census Bureau, the borough has a total area of 0.8 square miles (2.1 km2), all land.

Marion Center is connected to the villages of Deckers Point (via Deckers Point Road, concurrent with Main Street to the borough line), Dixonville (via South Manor Street, concurrent with PA-403 to the borough line), and Rochester Mills (via Richmond Road).

The first is very narrow, being small enough to easily step across, and drains the east side of the hill in the southeast section of the borough.

The second drains the west side of the same hill and connects to the main flow behind the post office near its intersection with South Manor Street.

All three minor water flows are perennial (though the very narrow one does dry up when rainfall is low) and have sources within the borough limits.

Pine Run connects to Crooked Creek (a tributary of the Allegheny River) about five miles (8 km) south of the borough.

On June 21, 2002, Sam Erwin walked into the school district office with a .32-caliber pistol.

Indiana County police said the incident concerned a dispute Erwin had with the district over his wife, Nancy Erwin (formerly Mogle), an eighth grade algebra teacher, losing her teaching position in 2001 after teaching for 21 years.

Instead of closing, Marion Center Bank pulled its screen down half-way and continued to operate.

Today, the bank has seven locations across Indiana, Jefferson, Armstrong, and Cambria counties: Dayton (1997), Big Run (1997), and Punxsutawney (2000).

Marion Center Bank's corporate headquarters is located at 1271 Indian Springs Rd in Indiana, PA. As of the census[10] of 2010, there were 451 people, 173 households, and 129 families residing in the borough.
