Busan: Exploring the city of a hundred lighthouses - SilverKris

"Sitting atop one of a group of five rocky islets, this compact, castle-like lighthouse rises directly from sheer rock and is best reached by boat drops that also service hobby fishermen and the adjacent breakwater. From its upper levels, clear days afford views all the way to the Japanese island of Tsushima; the structure’s solitary, windswept setting and dramatic approach emphasize both the raw power of the sea and the lighthouse’s traditional role in coastal navigation. It was recently automated, removing its resident keepers, which only adds to its remote, self-sufficient mystique." - Matthew C Crawford
