Since the era of the Three Kingdoms, tombs served as graves of members of the upper class
The ancient tombs around the Yeongsan River have a unique pattern, different from those of the areas. Especially, the shapes of the graves vary from round to square and some have square foundations. Recently, more tombs with square fronts and round backs have been discovered.
The ancient tombs of Yongdu-ri with square fronts and round backs, investigated by the research team of the Koraen Mental Culture Institute in 1986, are recognized as similar to the ancient tombs in Janggobong, Bingsan-ri. It is estimated that this tomb was constructed in the 4th century. This site was discovered due to an illegal excavation in February 1995. It Janggo-bong.
The dimensions of the tomb are: front - 15.2 meters long, 17 meters wide and 3.5 meters high, and back - 23.8 meters long, 20.5 meters wide, and 4.5 meters high. The lengths are 38.2 meters to the east, and 41.5 meters to the west. This place is valued as a valuable research site to aid in understanding ancient relationships between Korea and Japan

Jiseokmyo, along with Seondol, are major relics of the megalithic culture. These types of structures are found throughout the world and are often called Goindol (Dolmen).Korea's Jiseokmyo are classified into the northern type, which has the burial chamber above ground, the southern type, which has small support rocks sustaining a cover rock(like a Baduk table) and the Gaeseok type, which has a cover rock on the ground with the chamber buried underground.
The Jiseokmyo of Yeonjeong-ri are located in a flat, narrow valley near Namhae; there are a total of 48 pieces. Most of them are of the southern and Gaeseok types. They are concentrated in a northeast to southwest direction and small Jiseokmyo surround large Jiseokmyo. Haenam-gun has a total of 88 Jiseokmyo sites and 830 pieces in all. Yeonjeong-ri, along with Bangchuk-ri of Hwasan-myeon, has the most Jiseokmyo. The largest one is 5m in length and there also are 19 other considerably large ones that stretch over 3m.
There are 48 groups of Jiseokmyo concentrated in a narrow region of southwest Korea. It is an important resource for us in understanding the tombs from the Bronze Age.

This shell heap consists of seashells that people discarded after extracting the sea animals used as food.
This place was first known in 1983 as a dwelling place of people in the Iron Age. Through three excavation surveys conducted since 1986, various shells, bones, pottery shards, iron ware and housing sites were identified.
The shell heap extends 300 meters in length and 200 meters in width and is the biggest such relic site along the area of the southwestern coast especially the Hwacheon. One of the bills from the Chinese Shin Dynasty was found to help estimate the time in which the relic site took shape. Among the relic areas of those times are the Neukdo Shellheaps. comparable to the Gimhae shelleaps. the Seongsan Shelleaps in Masan, and the Gwakji Shellheaps in Jeju.
This relic site and the Dumo Shell heaps in the Baekpoman area, are two important ones to help explain the ancient culture of Haenam Province.

The word ‘Gobun’ refers to the tombs of people of high social standing from the Age of the Three Kingdoms.
This Gobun is located near Doksuri-bong (a mountain summit that is 57.7m above sea level) to the southeast of Yongun Village. There are two Gobun located 2m apart from each other toward the southwest. Located on top of a basin and along the mountain range, it is a good place from which to observe the surrounding landscape.
The first Gobun, on top of the basin, has a 2.2×0.8m rectangular hole. The Gobun is rounded and is 15m in diameter and 1.8m in width. The second Gobun, on the southwest corner of the basin, has been flattened and is barely identifiable. This Gobun is also rounded and is 12m in diameter and 1.5m in width.
As no relics have been found around the Gobun, further excavation would be needed to identify whether it is an Onggwanmyo (a tomb in which the corpse is sealed in a jar) or a burial chamber.

The word ‘Gobun’ refers to the tombs of people of high social standing from the Age of the Three Kingdoms.
This edged Gobun, located on a northern hill of Mt. Seongma, was first discovered and introduced to academic authorities in 1986. The tomb is rectangular shaped from the very bottom and is supported by rock inserts that are densely placed around the tomb. It is therefore called the ‘Edged and Slanted Rock’ Tomb. From the outside, the tomb is 16.5m in length, 14m in width, and 1.7m in height.
The academic sector has focused on the fact that this type of tomb is found only in this region, which is the southern most part of Korea. Along with the Front-edged and Rear-rounded Gobun located on Mt. Janggo of Yongun-ri nearby, it is an important historical relic, which that can clarify the interaction of the Gobun culture of ancient Korea and Japan and the history of the Jeonnam region's old Gobun.
