Editing Marion, Indiana (section)

===Modern history===
Marion's prosperity plateaued between the end of the gas boom, just prior to [[World War I]], and 1955. But construction of a [[General Motors]] stamping and tool plant created many new jobs. The city grew rapidly. Except for bedroom communities near metropolitan centers, Marion's growth during the 1950s exceeded all but one Indiana city with populations of 10,000-100,000.

In the late 20th century, Marion surveyed its significant properties and defined the main buildings and grounds of the hospital as the Marion Branch Historic District. It is located at the intersection of 38th Street and Lincoln Boulevard, approximately {{frac|2|1|2}} miles southeast of the center of Marion. The boundaries are 38th Street on the north, the railroad right-of-way on the east, the [[Mississinewa River]] on the southeast, Chambers Park on the south and southeast, and Lincoln Boulevard to the west. The {{convert|212|acre|km2|adj=on}} site is roughly square in form with diagonal boundary lines on the southeast and the southwest eliminating those corners of the square. Originally, farming operations on the home grounds included the area that is now Chambers Park. In 1981, a Determination of Eligibility for the National Register of Historic Places for Federal Properties was made under Criteria A and C. As a result, since 1981, various projects have been reviewed by the Indiana State Preservation Office for compliance under Section 106 of the National Historic Preservation Act of 1966, as amended. In 1992, the historic district was surveyed by the Indiana Department of Natural Resources as a component of the Grant County inventory of historic sites and structures.

One of Marion's more notable architectural landmarks is the extensive Marion High School campus, which includes a 1,468-seat community auditorium, home of the Marion Philharmonic Orchestra, the Community School for the Arts, and the Mississinewa Valley Community Band. The city has a lending library, the Marion Public Library.<ref>{{cite web|url=https://www.in.gov/library/files/countyindex13.pdf| title=Indiana Public Library Director|publisher=Indiana State Library| access-date=7 March 2018}}</ref>

The eight-time state basketball champions, Marion Giants, play in the 7,500 seat Bill Green Athletic Arena. The city operates a {{Convert|2.75|mi|km|adj=on}} Riverwalk from downtown to Matter Park, and there is a newly renovated $9,000,000 YMCA Memorial Coliseum to honor war veterans. This was the previous home of the Giants, which was built after their first State Basketball Title in 1926.
 
A publicly owned mansion, the Hostess House, is used for social functions, and Marion General Hospital has been nationally accredited for approximately a half-century. Marion General was recently named a magnet hospital.
