Lancaster Castle has closed as a prison and re-opened as a tourist attraction with a cafe. We can now freely walk in and out of the gate. It is like visiting Hell after Christopher Rudd closed it near the end of Mike Carey's Lucifer.
However, prisons still exist elsewhere in England just as Hell continues to exist in other parts of the human imagination including John Constantine: Hellblazer, written a short while ago by Andy Diggle whose workshop is just below the Castle to the left of the attached image.
The Castle has several recent, well-attested, horrific ghost stories warranting both psychic investigation and graphic dramatization.
