Calliseom’s Underground AI Campus

Field notes

The project describes a six-part infrastructure chain covering power, facility operations, connectivity, GPU compute, cloud services, and client delivery. Its physical proposition is unusually specific: four underground floors at 16–20 metres, a claimed groundwater buffer 52–60 metres below ground, dual 220 kV power, and dual 400G connectivity. The site also lists a staged capacity plan beginning at 10 MW and extending toward 1 GW, although these figures and the stated approvals remain claims presented by the project.
