  • Describe the history of the lighthouse

    As with all Korean lighthouses this has been very difficult to find any information about and also to pinpoint the exact position. I am unsure if the original 4th order Chance optic is still in use as I have been unable to find any history relating to the site. I have been unable to find a photo of the lighthouse anywhere but this may be explained by the fact that the lighthouse is situated close to North Korea's missile test centre at Musudan.
