Celina City Hall was built in 1800 at the northeast corner of Lovingston and Main Streets. It exhibits the characteristics of the Richardsonian Romanesque style of architecture popular in the late 1800's, including a large asymmetrical design, hip or gable roof lines, cut stone or brick features, and a rounded Roman sandstone arch entryway. An unusual aspect of the structure is its tall octagonal tower, said to resemble a lighthouse, possibly because of Celina's location on the lake. Because this architectural style was based on such large scale and heavy appearance, it was expensive to build and was used primarily for public buildings. When Celina City Hall was constructed, it housed the city and township offices and supported the fire and police departments. The city jail was located on the first floor, and the second floor at one time housed an opera house.
