This tower was likely built as an observatory (best fit theory) or an above-water forge (low probability alternative). The upper tower has been extensively rebuilt.
- Approximately 1000 years old; continuously renovated until circa 200 years ago when the upper tower was modified and the site abandoned - Built from bioconcrete poured over a metal framework, then electroplated with corrosion-resistant alloys - Fine grain structure indicates the metal was cold worked, without forging or smelting - Original design included an electrical system for pumps and gates, predating human commercial electricity by 650 years - Due to its later construction, the upper tower should be scanned and analyzed separately.
Evidence suggests this tower was built to raise telescopes above water for weather and sky observation. Structures in the interior may have been involved in mapping and modeling the local solar system.
Assesment: locate and repair original power supply to open the observatory. Pioneer-built generators are incompatibile with the alien electrical grid.
