Unfortunately Ancient Wonders are not able to be reinstated in the game.
Any building that a player can rebuild from the game is unable to be reinstated, so quite right @QFol2
We are able to reinstate Special Buildings like event buildings, as a one time gesture of goodwill as these cannot be built again.
Hope this clarifys the situation.

Thats a good example @Julian as this is a Special Building and would be granted back as a one time gesture of goodwill.
Rebuilding it would take a crafting recipe, as these are not available from the HUD panel to rebuild, so are classed as a Special Building @Pauly7
