National Wonders

National wonders are purchasable structures that, like nation improvements, provide various bonuses and advantages. Unlike improvements, national wonders do not have any set requirements (with the exception of the National War Memorial), instead coming at extremely high prices. Due to these extravagant prices, national wonders are not necessarily meant to create large returns for the investment; rather, they are there to add an extra layer of development and strategy for highly developed nations. Only one of each type of national wonder may be built by a nation, and only one national wonder may be built every 30 days. Each national wonder costs $5,000 in maintenance a day.
