I am sorry if I am not keeping my facts straight, but what I learned during the documentary I watched the work at the Cathedral halted around the 15th century so I was basing it in that era.
Yes, work halted in the 15th century but they only restarted construction in the 19th. So parts of the church have existed for hundreds of years, but the most iconic bits only exist 150 years or so.
That is right, sorry for the confusion I have given you and your readers. xD
don't worry about it :) Thanks for commenting!!
