The Northern Lighthouse Board's principal concern is with safety: the safety of the mariner at sea; the safety of our own people employed in or around some of the world's most dangerous coastlines; and the safety of the environment in which we, and those who come after us, must live and work. Today the Board is responsible for a network of over 200 lighthouses around the coasts and islands of Scotland and the Isle of Man. The Board’s main offices are in Edinburgh and there is also a base at Oban for berthing its two ships, NLV 'Pharos' and NLV 'Pole Star'. The paintings in the Board’s Edinburgh offices reflect our work; the memorable painting ‘Building of the Bell Rock Lighthouse’ by Alexander Carse is featured on the jacket of the 'The Lighthouse Stevensons' by Bella Bathurst.
