Bird of Prey?

Awhile back I came across this nest and didn’t see the original architect or any evidence of the occupant at the time. I did take a few pictures so maybe somebody can help me out and tell me what they think this might be.

One of my thoughts was that it might be a Great Horned Owl, it looked like she did a lot of work building the nest but it kept falling down maybe due to the location and wind of the building. Any ideas? Comment below please!
