Songhak-dong Gobungun in Goseong-eup is a historic site where you can see the tombs of the ruling class of Sogaya from the Gaya period. Seven to fourteen tombs are distributed along the ridge, showing the burial method of first raising soil and then burying the body. It is open free of charge at all times, with a parking lot and restroom at the entrance, and the walking path takes about 15 to 20 minutes to complete one loop. In summer, there are almost no trees to provide shade, so it is hot on days with strong sunlight.
