It did have one church, a United Methodist Church, but it closed in 2008. The church building was built in 1865 and 1866 by Presbyterians/Congregationalists then later sold to Methodists. The building has since been renovated into a house and no longer resembles the original structure which used to be maintained by the people of the town on a volunteer basis before being sold by the Methodists.
