"Give Them More Light"

Written on a cell door in the block wing of Sligo Gaol, this graffiti was captured in 3D by Anderson Digital in March 2026. The Archaeological Impact Assessment prepared for the THRIVE renovation specifically recommended recording this graffiti, describing how it makes "an immediate visual connection with those incarcerated over the lifetime of the gaol."

Who wrote it, and when, is unknown. The words remain.

Peak occupancy at the height of the Great Famine. Nearly double the designed capacity. A school room, chapel, hospital and surgery had been added by then.

Gas lighting and piped hot water installed. The Gaol earns the nickname “The Cranmore Hotel.” Michael Davitt briefly imprisoned after the first Land League meeting.

THRIVE · €7 Million Awarded

Sligo County Council awarded €7m under THRIVE Heritage Revival Scheme, EU ERDF co-funded. Renovation plan: Governor's House as museum, cell blocks restored, new visitor centre.

March 2026

3D Digital Record

Anderson Digital × ATU Architecture capture the full site. 67–82 hours of machine processing. The pre-renovation record exists permanently.

The Panopticon Principle

Jeremy Bentham (1747–1832) proposed a prison where all inmates could be observed from a single central point. The prisoner never knows if they are being watched, so must always behave as if they are.

Sligo Gaol is Ireland’s finest surviving Panopticon, the Governor’s House at centre, cell blocks radiating outward. Architect Richard Ingleman adapted Bentham’s radical philosophy into functional Irish limestone.

Perhaps those three words scratched on a cell door, “Give Them More Light”, were a direct response to the very principle the building was built upon.
