Carcosa was designed with the commission of Balthazar Martin, current mayor of Attollo. Architect and Attollo native Henry Vespa, who worked alongside his wife Katherine, was the individual hired to complete the design. Basing off the results of Void 1, the original prison that was hastily set up to hold powered individuals as well as the supernatural, Henry and Katherine sought to improve the security and resilience of the new prison. 

 

Carcosa resembles the panopticon that was originally proposed by Michel Foucault in 1977 (9 years before The Rapture). The panopticon design focuses heavily on the idea of a surveillance of many by few; the prison is designed in a circular (or, in Carcosas case, triangular) style where a guards stand at a viewpoint in the center that permits them to observe every inmate in their cell 24/7. The cells of Carcosa themselves vary depending on the level (higher levels tend to have more heavily modified cells as compared to lower levels) but all cells have a 2 way reflective door; the guards can see the inmates, but the inmates cannot see outside of the cells.
