I've always loved this Cathedral. "The Sagrada Familia" in Barcelona. The architect Antoni Gaudi's vision was generations ahead of it's time, and his Cathedral will still be there a 1000 years hence.
...likely 'several' thousand.
We are beings of faith though the objects of our faith changes like clouds in the swift winds of autumn. However these are just the symbols the totems we use for something beyond our knowing.
Places like "Sagrada Familia" are where we are reminded that we are all,...that's 'all' part of something Vast, and Wonderful.
