Stellaris Megastructure IDs

A complete and up-to-date searchable list of all Stellaris megastructure IDs.

Megastructures are colossal constructions. Expensive and time-consuming to build or repair, these remarkable feats of engineering are nonetheless important wonders that provide large bonuses, demonstrating the technological and economic primacy of the builders' empire.

They cannot be built in orbit of a celestial body that has an uninvestigated anomaly. All megastructures except Gateways are destroyed if a Star-Eater destroys the system.
