Buildings are constructible objects built by players that provide population, points, and/or income (stars). Buildings include resource buildings, monuments, temples, and roads. Each building can only be built on specific terrain types.

Structures are generated objects randomly dispersed across the map during the world generation. Structures include cities, villages and ruins. Resources and terrain are not considered structures.
