They may have been the largest in Ireland, but the city’s fire engines could not save Blackrock Castle on the night it burned down. Pat Poland explains why Cork’s fire engines were useless on the night


‘Old Blackrock Castle, with majestic
Salutes by day, and guides our
boat by night.’

So wrote local poet and lawyer Henry Bennett, alluding to the lantern on the castle that served as a beacon of comfort to the fishermen abroad on Lough Mahon in the darkness of night.
