This place is not a place of honor... no highly esteemed deed is commemorated here... nothing valued is here.

What is here was dangerous and repulsive to us. This message is a warning about danger.

The danger is in a particular location... it increases towards a center... the center of danger is here... of a particular size and shape, and below us.

The danger is still present, in your time, as it was in ours.

Maybe a few blocks of brutalist buildings would work better than the spikes.

Just fill their insides up with solid concrete, to prevent people from entering them and having their souls sucked out.

I don't want to live in a building that looks like a bunker. At least put some arrow slits in and add a portcullis if you're going to do that.
