Breakdown of wonders
A large number of the known wonders of the universe were structurally-based wonders, notable for their large physical size (The Spire of Canopus IV) or size of information held (Library on Kar-Charrat. (PROSE: Ghost Devices, AUDIO: The Genocide Machine)

Much like the Library on Kar-Charrat, other notable wonders of the universe are information stores or notable museums, the Braxiatel Collection was noted a noted location for rare and unusual items for much of its existence, for humans the Museum and Archive of the Tellurian Stain was notable as it tracked humanity's expansion through the universe.
