Shawken Spire

The Shawken Spire was a super-tall skyscraper on the planet Shawken. Construction of the building began before 25,780 BBY and over more than nine millennia that followed it eventually reached low-orbit altitude. The building was destroyed in 18,780 BBY but reconstructed thereafter with more modern materials. It was included in the list of the Twenty Wonders of the Galaxy by the historian Vicendi in his 10,000 BBY publication Arturum Galactinum.
