 
The position of the Southstack lighthouse is 53 18.4N 04 41.9W 
  Captain Hugh Evans was not the first to realise the importance of a lighthouse at this point, the first representation for a light at this point was made 1665 to King Charles 11. This representation was rejected. Therefore Captain Hugh Evans had to prove this lighthouse was desperately required so he collected and produced to the government of the day all the maritime accidents around the coast over the previous twelve months, drawing diagrams and maps of these events. Such overwhelming evidence of the importance and necessity of the lighthouse was produced that the go ahead to erect the lighthouse was sanctioned almost immediately . This construction of this lighthouse was to prove to aid the safety and prosperity of the mariners from all around the world even to this very day and for many years to come.

  The height of the light above the mean high water level is 60 metres.
