Mostly completed by 1880, but the tower was completed in the early 1900s and there have been other additions as well. Geologically speaking, it is either the Columbus Limestone, the Delaware Limestone, or a combination of both. Although this stone was sold under the name Sandusky blue stone, it is certainly not blue today. Most of the church is limestone, but the top of the tower and most of the trim seen here is sandstone. The rock-faced stone blocks are set in courses.
Some fossils are up to two centimeters or greater in diameter.
Much of the base of the building, the top portion of the bell tower, and original trim, for instance around windows, is Berea Sandstone. The steps are also sandstone, but these are not the original steps. Many details sculpted in Berea Sandstone, including the drove-work dressing of the windowsills and the band of sandstone near the base of the building, are still in very good shape. However, some of the lower sandstone features around the entranceways are pitted from sandblasting done in the 1990s. Outer layers of many of the limestone blocks have weathered away and the originally pitched edges of some limestone blocks are barely visible.
