Editing National Parks (section)

==Requirements==
National Parks can be built on a cluster of any four contiguous [[Tiles|hexes]] that meet the following requirements:
* The [[terrain|tiles]] must be [[Natural wonder|natural wonders]], [[Mountains]], or a tile with an [[Appeal]] of Charming or better.
* All four of the tiles must be owned by the same city.
* The tiles must form a  (vertical) diamond shape (not a slanted diamond).
* No tile can have an [[Tile Improvements|Improvement]] or [[District]] on it.

With the Naturalist active, zoom out and view the map - any usable areas will be highlighted in white. Use the Appeal lens to find areas that are almost usable, and might just require you to purchase another tile, or plant a forest to raise appeal.
