How do I recall honor structures?

I don't think there is a way to recall them yourself. They will be recalled automatically if the alliance center they are next to is destroyed or demolished.

You can relocate them. If you want to move it to a different tile. To do this tap on the building itself in the world and select 'View'. Then at the bottom of the information screen will be a Relocate Button.

Relocating it will cost stone and will damage the building which then costs rss to repair.
