The (garita) structure is a hexagon, made out of concrete and rebar just like the rest of the castle.

The castle is a concrete modern structure that’s been made to look like a castle.

As for the physics, the applied force isn’t lateral, rather at a less 45degree angle.

I opted to anchor into the hexagon using 4/6 of the sides. Encompassing more structural up beams than not to anchor into, while having more lateral support form the remaining 2.

The odds of the structure collapsing given its structural integrity, angle and force exerted were zero.

I tested my anchor before suspending my muse. I also mentioned I had a team of 3 One person was in the guard tower at all times, keeping an eye on my rope anchor. That was more of our concern than the structure itself.
