It began as an 1865 brick residence and was converted and enlarged into a hospital in 1921.","why_significant":"The nomination argues it is a rare example of home-like community health care in the early 20th century, as Mercer County's first hospital, founded in 1915 by Dr. Lloyd M. Otis. It is also architecturally notable as a Civil War era residence remodeled into an adapted prairie style by the Lima firm Hulsken and Strong. The hospital's 1921 appearance and interior arrangement largely survive.","narrative":"Otis Hospital, at 441 East Market Street in Celina, was Mercer County's first hospital. Dr. Lloyd M. Otis founded it in 1915, and his son, Dr. James J. Otis, ran it until 1977. The building began as a two-story brick residence of 1865 with wide classical pilasters and hooded segmental arched windows. A 1921 conversion added an east section with trios of multipaned windows, a red tile roof with wide overhangs, and horizontal lines resembling prairie style. The Lima firm Hulsken and Strong carried out the remodeling. Inside, the plan was meant to feel like a home, with operating and delivery rooms and patient rooms upstairs, and an office, x-ray and emergency rooms on the first floor. More than 6,125 deliveries were recorded over 55 years of maternity care. Fire safety rules ended maternity care in 1970 and Medicare services in 1976, and in-patient care stopped in 1977. A planned demolition for a fast food restaurant was cancelled after public objection, and rehabilitation is now being sought.","period_of_significance":"1800-1899, 1900- (specific dates 1865, 1921)","architect_builder":"Hulsken & Strong, Lima, Ohio","architectural_style":"Adapted prairie style remodeling of a Civil War era classical brick residence","criteria":[],"status_note":"Closed its in-patient services in 1977 and is listed as unoccupied.
