4.  Cathedral Church of St. John the Divine – United States

The largest church in the United States, the Cathedral Church of St. John the Divine went into construction in 1892.  Over the years, the style of the Cathedral changed, so construction continued.  Various wars interrupted completion, and then a large fire in 2001 necessitated further construction and restoration.  The church has been nicknamed, “St. John the Unfinished”, as it is still undergoing renovation and repair.  The interior space currently measures just under 121,000 square feet.
