Aigler Alumni Building
Also known as: College Hill School
Why it's listed
Built in 1912-1913 as College Hill School, an elementary school in the Tiffin School District, this three-story Jacobethan building at 315 East Market Street now serves Heidelberg College. It replaced an earlier schoolhouse that stood directly in front of it. The brick walls are laid in Flemish bond over a plain ashlar foundation, and twin turrets with quoins flank the entrance bay. Buttresses separate the bays and stone beltcourses mark the floor levels. Numerous stone carvings decorate the entrances, including an owl, eagles, a boy with a sailboat, symbols of the 1912 political parties and signs of the Zodiac. The college bought the building in 1961, remodeled it for classrooms, offices and laboratories, and renamed it to recognize alumni support, particularly Allen G. Aigler, Class of 1902, a trustee from 1926 to 1960. It was listed as one of the campus buildings tracing the college's historical development.
Significance in brief: It was nominated as part of a thematic group of Heidelberg College buildings that trace the institution's growth and architectural development since its founding in 1850. The building was purchased by the college in 1961 and renamed to honor alumni support, especially trustee Allen G. Aigler. It also has distinctive stone carvings and Jacobethan detailing.

What listing means for this property
For an income-producing building, listing (individually or as a contributing building in a district) is the gateway to the 20% federal rehabilitation tax credit on qualified rehabilitation costs, often stackable with state credits. Work claiming the credit must follow the Secretary of the Interior's Standards and be approved in advance.
Listing does not restrict a private owner acting without federal money or permits; where federal funding or licensing is involved, Section 106 review applies.
