Not all of the Narbonne Cathedral is finished (the unfinished bit) and the above photo shows what there actually is. What would have just been the choir area was built, but the crossing area where the tower would have been and the rest of the nave weren’t finished.
This is what the cathedral looks like inside, all rather crammed in compared to what the original plans would have envisaged. The choir area has been pushed back to a small area at the rear and what is effectively the nave has been constructed in the space that’s been freed up. The proportions are now of course entirely wrong, as the height is way too high for the floor space, although that doesn’t take away from just how impressive this building feels.
I can’t help thinking of just how irritating it must have been for the architects to see their designs never quite completed.
