Civilization Wiki

Culture (Culture (Civ4).png) is one of the three kinds of Commerce a city can produce. It also determines your borders and can be adjusted along with Research and Espionage. Percentages that appear when hovering over land tiles show how much culture a civilization is exerting on that tile.

Culture Levels[]

Border growth is determined by Culture Level. Borders grow by 1 tile in all directions every time a city's accumulated Culture exceeds certain thresholds.
