Cheomseongdae is the oldest existing astronomical observatory in Asia. Constructed during the reign of Queen Seon-deok (632-647), it was used for observing the stars in order to forecast the weather. This stone structure is a beautiful combination of straight lines and curves, and was designated as National Treasure No.31 on December 20th, 1962. Cheomseongdae was built in a cylinder shape with stones 30cm in diameter. 362 stones were piled up to make 27 levels. Roughly 4.16m up from the bottom there is a 1㎡ square entrance and a space to hang a ladder under it. The inside is filled with soil up to the 12th level, and the 19th, 20th, 25th, and 26th levels all have long rocks hanging on two areas, shaped as the Chinese letter '井' (jeong). It stands 9.17m high and the base stone on each side measures 5.35m. The Vernal Equinox, Autumnal Equinox, Winter Solstice, Summer Solstice and the 24 solar terms (also known as the astronomical solar year) were determined by the observation of stars. The pavilion stone is believed to have been used as a standard of deciding directions, north, south, east and west. The 362 stones used to build Cheomseongdae represented the 362 days in a lunar year.

One of the amazing things about Seoul is that some of the most interesting historical sites are right in the middle of the business districts. Located near the Jongno Police Station and the Japanese Cultural Center, Unhyeongung Royal Residence is one such site. Unhyeongung Royal Residence was the home of young Gojong, who later became Emperor during the Joseon Dynasty. Under order of Queen Mother Jo, Unhyeongung was renovated into a grand, palace-like house with four gates. Gojong’s father, Yi Haeung, or better known as Heungseon Daewongun, continued to live at Unhyeongung for most of his life. Damaged during the Japanese colonial period and the Korean War, the Unhyeongung Royal Residence seen today is a much smaller version of the majestic structure that it used to be. Entering through the front gate, the first noticeable sight is a small row of rooms to the right. This area, called Sujiksa, housed the servants and guards. To the front, left-hand side of Sujiksa is a structure called Norakdang. Many important events, such as birthday parties and ceremonies, as well as the wedding ceremony for Gojong and Myeongseong, were held here. To this day, traditional wedding ceremonies continue to be held at Norakdang. Norakdang also served as one of the two women’s quarters. The most notable structure inside Norakdang is the kitchen, which was used for food preparation when hosting important events. Right outside Norakdang, there are several rock structures along the path to Irodang. The rock structures are said to resemble various animals. To the left of Norakdang lies Irodang, the main building of Unhyeongung. This was where the wife of Heungseon Daewongun resided. Irodang's most prominent feature is its tall steps and square shape. It was built this way in order to help protect the women inside from intruders. Outside Irodang lays an old well on one side of the wide, open yard. To the right of Norakdang lies Noandang. Noandang served as the men’s quarters and was where Heungseon Daewongun received his guests. The word noan means "old man" and carries with it the connotation of comfort and ease. Thus, it served as the leisure quarters for the men. However, Noandang was not just a place of rest and entertainment. As the father of a young Emperor, Heungseon Daewongun carried out all his business from Noandang. Upon exiting Noandang, there lies an Exhibition Hall to the far right. The Exhibition Hall houses a small collection of interesting artifacts and information. Items such as a scale model of Unhyeongung, writing tools, traditional wedding garments, and more, can be seen here. Next to the Exhibition Hall, there is also a small coffee shop and tea room where visitors can enjoy a nice beverage while taking in the sights of Unhyeongung. 

Located between Haeundae Beach and Gwangalli Beach, the Millak Waterfront Park is the first park in Korea to combine the oceanfront with public rest and leisure facilities. The park (about 33,000㎡) can accommodate up to 40,000 people and boasts convenience facilities such as gardens, shaded rest areas, and benches. The 3,040㎡ platform from which visitors can overlook the beach also serves as a place where people can dip their feet in the ocean when the tide is high.

Situated to the north of Jeju City, Yongduam was created by strong winds and waves over thousands of years. However, there are plenty of other stories of how it came to be. One legend has it that a dragon stealing precious jade from Mt. Halla was shot down by an arrow from the mountain deity. When he fell down on Yongduam, his body immediately sank into the ocean and his head rapidly froze looking at the sky. Another legend has it that a white horse, who dreamed of being a dragon and ascending to the sky, came to be caught by a soldier and froze into the rock.From Yongduam, visitors can see Haeneo women divers working on catching seafood. Near the rock are various cafes, bars, and restaurants. The coastal road between Aewol-eup and Yongduam is a popular spot for couples. Cafes and seafood restaurants began to appear there five years ago and now form a pleasant café village.Drinking a cup of coffee at the village café and driving along the scenic coastal lines, visitors can encounter Iho Beach where black rocks contrast with the emerald-blue ocean, Hagwi Coast, and Aewol Port. Aewol Port is also home to small seafood restaurants and fishing boats coming in and out, adding flavor to the coastal drive. Further from the port is one of the most popular beaches on Jeju Island, Hyeopjae Beach, showcasing the deep royal-blue sea year-round with splendid white sand. 

Situated on the southern part of Hangang (Han River), Yanghwa Hangang Park stretches along between the mouth of Yeouido Saetgang Tributary and the Gayang Bridge in Gangseo-gu, Seoul. This spacious park is lush with vegetation and offers a spectacular view of the river.The park is located nearby a number of other attraction including Seonyudo Park (an island in the river, which has been transformed into an ecological park), Seonyu Bridge, and the World Cup Fountains (with jets 202m in x_height).There is a wide bike trail that runs through the park that connects this park with the other Hangang River Parks. Every May, the bike trail is flanked by lush green grass and beautiful roses, making it the ideal picture-taking spot for friends, couples, and families. 

Igidae Park faces Jangsanbong Peak which is included in Yongho 3-dong. After passing one hill between Yongho Sewage Treatment Plants and Igidae, the east side where the peak (225.3 m high) can be seen has picturesque scenery, created by uniquely shaped rock cliffs, but it is too dangerous for tourists to visit. Therefore, visitors can take a ship in order to enjoy the scenery. The center of Igidae looks almost flat and seems to be leaning against the mountain which is linked to the sea for about 2km. The scenery including waves crashing into the rocks is fantastic and the area is also a suitable fishing spot. The area was used as a military operation area so civilian access was prohibited until 1993.

Just south of Gyeongpo Beach is Chodang Sundubu Village, which is famous for sundubu (watery tofu). Along Gangneung's most famous food street the beans are ground for Chodang sundubu, then through several steps, salt water from the East Sea is used in the congealing process resulting in a soft and light tofu. The name of this village, Chodang, originates from the name of a famous family that once lived here known as Chodang-Heoyeop. Heoyeop was the father of son, writer/poet Heo-gyun [1569~1618] and daughter, poet Heonan-seolheon [1563~1589]. A traditional-style Korean house has been reconstructed on the site where the original house of Heo-gyun and Heonan-seolheon once stood.
