The cathedral, designed in 1888 and begun in 1892, has, in its history, undergone radical stylistic changes and the interruption of the two World Wars. Originally designed as Byzantine-Romanesque, the plan was changed after 1909 to a Gothic design. After a large fire on December 18, 2001, it was closed for repairs and reopened in November 2008. It remains unfinished, with construction and restoration a continuing process.
This was one of the must-sees of my visit to NYC. It was a nasty cold day but the cathedral is amazing.
