Old New-Gate's underground workings produce two persistent visitor accounts. The first concerns a face described as visible in the rock at the location of a historical ceiling collapse. Local oral tradition holds that a miner or prisoner was killed in the collapse, and that the rock formation has since been read as a death mask. The geology of the limestone-and-copper deposit produces irregular faces and shapes throughout the workings; whether the specific feature corresponds to a documented fatality is not established in archival records.

The second account is the death of an unnamed prisoner during an escape attempt. Local reports describe him as the last man killed at the prison, attempting to climb a rope up through a well shaft when the rope failed. He died from impact or drowning in the well below. The Connecticut Department of Economic and Community Development's interpretive materials acknowledge a history of escape attempts and on-site deaths but do not single out a specific final fatality.

The site does not host overnight investigations or marketed paranormal tours, though it does run an October Jack O'Lantern program in the underground spaces - an interpretive event rather than a paranormal one.
