About six miles east of Grove, in the unincorporated community of Cayuga, stands a small stone Catholic church built in 1896 by Mathias Splitlog, a Wyandot businessman who had become one of the wealthiest Native Americans of his era through mining and land deals. He commissioned the church for his wife and the local Catholic congregation, and built the Splitlog Railway to carry stone and worshippers to the site.
The church is listed on the National Register of Historic Places and is one of the few intact pieces of Wyandot heritage left in the region. It is usually locked, but the exterior — solid limestone block, a single bell tower, set in open pasture — is reason enough for the short drive out.
