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, the Torchwood Estate, or another Torchwood facility is unclear. Thus, the Pyramid could be located in London, Cardiff, Edinburgh, or rural Scotland.
