Culligran Power Station - Vent Shaft
Culligran has a vent shaft, driven up from the gable end of the machine hall cavern. It's a plain shaft, it contains no fittings, stairs or ladder, it's purely for ventilation. At the lower end the opening is guarded by drip-catching metal tray, clearly visible in the picture below. I suspect this is a relatively recent addition. The upper end of the shaft is surmounted by a small concrete building, which has door and louvres for ventilation. Access to the shaft would be via the crane from below, or by abseiling the shaft from above.
