Daehang Port Gun Fort Cave, Gadeokdo

Gadeokdo Island was fortified by the Japanese military for 41 years, from the Russo-Japanese War until the end of the Pacific War, and traces of that war can still be seen in various places on the island. Daehang Port Artillery Cave is an artificial coastal cliff cave about 1944 meters high that was built in 175 towards the end of the Pacific War to house Japanese field guns.

As you descend to Daehang Port and turn right, you'll see a long wooden deck along the coast. As you walk along the deck across the sea, you'll soon come across a model of a huge cannon barrel jutting out from the cliff. Beneath the cannon model is a model of the Japanese army from that time and information on the situation at the time, and inside the cave is a model of the labor site where Korean laborers were forcibly mobilized.

As you walk along the colorful lights inside the cave, you'll come across information boards explaining about other artillery positions built by the Japanese military at the time and Japanese buildings that remain on Gadeokdo Island. There are two more smaller caves at the end of the cave.
