On October 30, 1878, a church was built at a cost of $2,408.00. In 1903 a Sabbath Schoolroom was added to the church parlor on the south side. Between the years of 1912 and 1919, the church was further improved by adding the basement classrooms, the kitchen and dining room. The vestibule and cement steps were added as well as a new organ. At this time, the name was officially changed to The First Presbyterian Church of Adena. The church no longer stands on what is now known Church Hill. Most presbyterians attend the Harrisville church.

Another Adena renowned church was the Methodist Church. The first church in the vicinity it was originally called the Holmes Church. It was built on land that was a government grant to Jacob Holmes who was an Indian Scout for the Government. It was the first church building erected west of the Ohio River of that denomination (in 1803) on the banks of Short Creek. In 1810, a new church was built one half mile from the first on higher ground. In 1829 an unfortunate division took place resulting in the building of a Methodist Protestant house one-mile away called, Rehobeth. The trustees agreed to build a new, more commodious house and completed in November of 1874, was Holmes Church (No.3). It cost $3200 and only a debt of $200 remained on dedication day. The amount was satisfied after that day. It closed in 1927. and was dismantled in the early '30s by Laszo Bonovich who operated a lumber yard at the West End of Adena across the creek from the site of Hagan's Mill. Prior to its destruction in 1901, a daughter of the Holmes Church was built. Recognizing a need for a new church, Rev. Holmes, and trustees built the Methodist Church of Adena. Built in 1902, on E. Main Street, the Adena United Methodist Church is active still today.
