Can wonders be destoryed if a city is taken? I seem to have kept most wonders. The Russians built Machu Pichu in one of their cities. It was pretty sweet, I could see the wonder peeking up from the tops of the clouds and the sun glinting off its snow capped peaks.
But after a few turns of taking cities, I noticed it had disappeared! I checked all the cities within 2 tiles of the mountain and none had the wonder any longer.
it may have only been under construction. wonders appear on the map when theyre under construction, even if they have not been completed yet. if you capped the city the construction would be halted and it would disappear
