Are there any background walls which are immune to explosives?

Question

Explosives are powerful. Maybe a little too powerful for my liking.

I've set up a trap where mobs fall into a pit of explosive proof material (in this case, mythril ore), where I'm free to throw dynamite or bombs to my heart's content.

However, I want there to be a background wall so that mobs won't spawn inside the pit while it's closed off (using active/inactive stone blocks).

So far all my attempts have failed with the background being blown clean off the sky.

Is there a wall that will remain in place even if dynamite goes off right in front of it?

Answer

I'm pretty sure the answer is no. The only background walls completely impervious to anything are world-generated, unsafe walls (unless the blast reaches a hole in the wall, or an edge). However, these, by design, cannot be placed by the player at all, and in any case do not prevent monster spawns.

It looks like you're out of luck here. Bombs and Dynamite can blow up any player-placed wall.
