The original building on this site was constructed in 1825 by Hezekiah Hubbell. While owned by different individuals, it was always used as a hotel. Several additions were made to the building which was finally sold to the Monumental Building trustees in the fall of 1873. This building would be razed for the construction of the current facility.

A fund was started in Sidney, Ohio, by surviving soldiers and their friends after the close of the Civil War. The initial desire was to erect a marble shaft to memorialize the war dead; but, when an anonymous letter to the editor suggested a building instead, a lottery was conceived to raise money for this project.

The lottery was not successful, with only 38,000 of the 60,000 tickets sold at one dollar each. Carey’s Hall (corner of Poplar and Ohio Avenue) was first prize. In April, 1875, the public voted overwhelmingly to issue bonds to pay for its construction. The $58,000 building costs were covered by two bond issues.

In June of that year, the cornerstone was laid for the memorial that would not only honor the dead, but would also benefit the living. H.H. Lane of Cleveland drew up the plans for this 3-1/2 story Victorian Gothic Monumental Building.

Completed in 1877, this building housed town and township offices, the municipal court, the horse-drawn fire department, police department, waterworks office, and post office. The ground floor contained a stable for the horses. The third floor also included an opera house where traveling troupes of the day performed. The two long flights of steep stairs did not deter performers and discourage those attending. To view a specialty act, adults paid $.25 and children $.10. The seating capacity was several hundred people.

On the other side were three marble plaques inscribed with the names of Shelby County’s fallen war heroes where the Neal Post of the GAR (Grand Army of the Republic) met regularly.

These plaques were created due to an act by the Ohio Legislature, which in 1871, had authorized the inclusion of a permanent tablet, in Civil War Soldier’s Memorials, which would hold the engraved names of each soldier who lost his life in conflict.

Cut in polished marble and etched in gold, the names of 309 brave soldiers speak a silent tribute to their ultimate sacrifices. Taking nearly a decade to complete, the tablets were formed from information supplied from comrades, families, military records and other sources. The local newspapers of the time carried articles urging those who had lost someone in the conflict to provide information.
