9. The Cathedral was never finished
A Guide to the Cathedral from 1921 posited that it might take 700 years for the Cathedral to be completed, since it was employing true Gothic building methods. However, as of now it appears that the Cathedral will never be completed. A “temporary” ceiling consisting of tiles is still in place a century after it was supposed to be demolished so that the Cathedral’s spire could rise.
Additionally, the crossing was never completed, resulting in an extremely truncated cruciform layout. (For photos of what the Cathedral was supposed to look like upon completion check out our previous coverage in The NYC that Never Was: The Half-Finished St. John the Divine.)
