Great Cobalt Pyramid
From Tardis Wiki, the free Doctor Who reference
The Great Cobalt Pyramid was a building built on the ruins of the old Earth Torchwood Institute. (DW: Bad Wolf)
- Whether this refers to Torchwood 1, Torchwood 3, the Torchwood Estate, or another Torchwood facility is unclear. Thus, possible locations of the Pyramid include London, Cardiff, Glasgow, or rural Scotland.
