The Kalavian Ruins were left behind by the Great Race that once inhabited the Lacuna Expanse. No one knows exactly what did it do or was designed to do, but it does resemble an ancient theatre. Anyway, they still hold great mystery and wonder today, attracting tourists, while bringing a sense of pride for citizens. If you were to find the Ruins on your planet, they would greatly increase the happiness of your citizens.

You can construct the Kalavian Ruins in the Archaeology Ministry by combining a Galena glyph with a Gold glyph.
