The lighthouses built by Robert Reading were at Howth Head, the Howth bar, the Old Head of Kinsale, Charles Fort (formerly Barry Oge's castle), Hook Head and the Isle of Magee near Carlingford, County Louth. The Howth bar and Isle of Magee lights did not last long, though the latter was reestablished on the Lesser Copeland Island. These lighthouses all had coal fires on their roofs.
In 1704 the lighthouses were compulsorily transferred into public ownership.
