This building at 1524 Elm Street traces its history to Holy Trinity Lutheran Church founded in 1849. The name of the congregation was eventually changed to Concordia Lutheran Church and in 1871 this Gothic Revival structure was built. In 1950, Concordia moved to Clifton and they are still there on Central Parkway. Prince of Peace Lutheran Church was eventually established by the Missouri Synod and located in this building. Concordia held services here in German until World War I and they still have German services once a month. Andrew Erkenbrecher, founder of the Cincinnati Zoo, was a member of the congregation.
I wasn't able to get too many good shots with the lighting but there were some very nice details inside.
