History

Soon after the village was platted in the early 1810s, a Methodist church was founded in the community. Today known as First United Methodist Church, this congregation built a small log church building in 1820; it was London’s first church. In the early 1900s, the church added facilities for the storage of human milk to sustain the orphanage it then operated.
