Goryeo porcelain was a pottery made during the Goryeo Dynasty, which refers to celadon made during the Goryeo Dynasty, such as celadon, white porcelain, black yuja, and iron yuja, but has generally been recognized as a reference to Goryeo celadon.

Goryeo celadon was developed under the influence of pottery from the Song Dynasty and its techniques were much better than those of the Song Dynasty, so the Song Dynasty people praised it as the best in the world.

The excellence of Goryeo celadon can be attributed to its beautiful color. Some are yellowish or yellowish brown, but others are especially beautiful.

There is National Treasure No. 115 of the celadon Sanggamdang First Gate Wan, which represents the period.

The tombstone of King Taejong Muyeol in Gyeongju is the tombstone of King Taejong Muyeol, the 29th king of Silla, which was built in the mid 7th century in Seorak-dong, Gyeongju, Gyeongsangbuk-do. It is also abbreviated as the Royal Tomb of King Muyeol.

The stele, which was erected during the Unified Silla Period, was shaped like a turtle, and the headstone on the stele was carved with a dragon. The tombstone of King Taejong Muyeol was the first example of this style.

On December 20, 1962, it was designated as National Treasure No. 25 of the Republic of Korea.

The construction of Seokguram Grotto was begun in 751 under the leadership of Prime Minister Kim Dae-seong during the reign of King Gyeongdeok of the Silla Dynasty, and was completed in 774 (the 10th year of King Hyegong’s reign), whereupon it was given its original name of Seokbulsa Temple.
Buddhist art reached its peak during King Gyeongdeok’s reign, which spanned the middle period of the Silla Period, Besides Seokguram Grotto, many other cultural treasures were built during this period, including Bulguksa Temple, Dabotap Pagoda, the Three-story Stone Pagoda of Bulguksa Temple, and the Bell of Hwangnyongsa Temple.
The artificial stone grotto was built halfway down Tohamsan Mountain with pieces of white granite. The principal statue of Sakyamuni Buddha was placed at the center of the grotto, and forty statues of various bodhisattvas, Buddha’s disciples, and guardian kings were carved on the surrounding walls, though only thirty-eight of them remain. The rectangular front chamber of the grotto is connected to the round main chamber by a corridor. The exquisite ceiling of the main chamber was made with more than 360 flat stones. The architectural technique used to build this grotto is unprecedented in its excellence. There are statues of four guardian deities on both the left and right sides of the front chamber, which functions as the entrance to the main chamber. Carved on both sides of the entrance to the corridor is a statue of the Vajra Guardians, while the narrow corridor is decorated with the Four Guardian Kings carved in pairs. There is an octagonal stone column on both sides of the entrance to the round main chamber. The Principal Buddha is placed slightly off center toward the back of the main chamber. From the entrance, the walls of the chamber are filled with the images of two devas, two bodhisattvas, and ten arhats. Standing behind the Principal Buddha is a statue of the Eleven-faced Avalokitesvara Bodhisattva, perhaps the most exquisitely carved statue found inside this grotto.
Every single sculpture contained in the grotto may be considered a masterpiece of East Asian Buddhist art. The list of masterpieces includes the principal image of Buddha, which was created with mature carving skills; the Eleven-faced Avalokitesvara Bodhisattva with its magnificently carved face and body; statues of valiant warriors and the majestic Four Guardian Kings; and the supple graceful statues of various bodhisattvas and arhats, each of which displays a distinctive individuality. In particular, the serene appearance of the Principal Buddha enshrined in the main chamber deepens the mystical atmosphere. The extremely natural appearance of the Principal Buddha seems to present to all living people the ideal model of a man harboring a profound and sublime mind deep within him and easily pass to them his everlasting mercy. Seokguram Grotto is a masterpiece of the golden age of Buddhist art in Silla. What makes it stand out all the more is its perfect combination of architecture, mathematics, geometry, religion, and art. Seokguram Grotto has long been preserved as National Treasure No. 24, and was jointly registered as a UNESCO World Heritage in December 1995 along with Bulguksa Temple.

It was also called Namdaemun because it was located in the south of the main gate of Hanyangdoseong during the Joseon Dynasty. It was built in 1396 (the 7th year of King Taejo's reign) and was the oldest wooden building in Seoul.

The building was rebuilt in 1448 (the 30th year of King Sejong's reign), and it was discovered that there was a big construction in the 10th year of King Seongjong's reign (1479) during the dismantling and repair of the building between 1961 and 1963.

Later, on February 10, 2008, the fire at Sungnyemun destroyed the roof of the second floor of the pavilion and partially destroyed the roof of the first floor. After five years and two months of restoration work, it was completed on May 4, 2013 and opened to the public.

This gate is a two-story building with a two-story square measuring 5 bays in front space and 2 bays in side space, with a rainbow-shaped gate in the middle of the stone pillars. The roof has a trapezoidal shape when viewed from the front, which is called the Woojingak roof. The multi-layered structure, which is decorated on the upper part of the pillars to support the eaves of the roof, is not only on top of the pillars but also between the pillars, and the composition is not too severe and is well-organized, showing the characteristics of the early Joseon Dynasty.

It is said that Yangnyeongdaegun wrote the Hyeonpan, which reads "Sungnyemun," in the book "Jibong Yuseol." It is the oldest wooden structure in Seoul that shows the exact date of construction.

ᄋ Sungnyemun's fire-fighting fire(2008.2.10)

- The 2008 Sungnyemun arson attack was a case in which the Sungnyemun building was burnt down from February 10 to February 11, 2008. The fire broke out around 8:40 p.m. on February 10, 2008, and the second floor of Sungnyemun collapsed around 0:40 a.m. on February 11, 2008, followed by a fire on the first floor, damaging buildings except stone pillars at 1:55 a.m., five hours after the fire.

Dabotap Pagoda and Seokgatap Pagoda (the Three-story Stone Pagoda of Bulguksa Temple, National Treasure No. 21) are the two most renowned pagodas in Korea. They are similar in height (10.29m and 10.75m), and stand facing each other, Dabotap Pagoda in the east, Seokgatap Pagoda in the west, between Daeungjeon Hall and Jahamun Gate of Bulguksa Temple . Dabotap is a unique type of pagoda, while Seokgatap Pagoda (also known as “Sakyamuni Buddha Pagoda”) is representative of the more general type of stone pagoda. The two pagodas were built at the same site to reflect the content of the Saddharmapundarika Sutra (The Lotus Sutra), in which the Dabo Buddha (“Buddha of the past”) stands beside Sakyamuni (“Buddha of the present”) to prove that his Buddhist sermon is right. Bulguksa Temple was founded by Kim Dae-seong’s offer in 751 (the 10th year of the reign of King Gyeongdeok of Silla).
Samguk yusa (Memorabilia of the Three Kingdoms) states that Kim Dae-seong built Seokguram Grotto for his parents in his former life, and Bulguksa Temple for his present parents. However, the temple was not completed at the time of his death, so it was finished afterwards by the kingdom, and in the end, the temple was run not for the private individual Kim Dae-seong but for the benefit of the kingdom as a whole.
Bulguksa Temple can be said to be the realization of the Buddhist paradise in which Buddhist monks of past, present, and future live together. It clearly reveals aspects of the spiritual world of the people of Silla. While it is perfectly clear that Seokgatap Pagoda is a three-story pagoda standing on a two-story platform, it is difficult to count the number of stories of Dabotap Pagoda. In fact, even experts have diverging opinions, with some saying it is has four stories and others that it has only three. However, the uniqueness of Dabotap Pagoda can be seen in the structure of each part. Stone staircases are attached to each side of the cross-shaped platform, with an octagonal pagoda body surrounded by square railings placed upon it. It is presumed that the pagoda was built in 751 during the construction of Bulguksa Temple.
This work is a masterpiece that beautifully expresses the complicated structure of wooden construction without any distraction by the use of through novel ideas. The work exhibits the artistic sensibility of Unified Silla through its well-organized structure consisting of squares, octagons, and circles, and in its length, width and thickness, which are standardized in every part. During the Japanese Colonial Period, the Japanese dismantled and repaired the pagoda around 1925, but they left behind no records of this work. In the process, Artifact, reliquaries, and other artifacts that must have been placed inside the pagoda all disappeared. In addition, of the four lions originally placed on the stone staircases of the pagoda, the Japanese took away three, all of which must have been in good condition. Though there have been continuous efforts to retrieve these precious cultural heritages, no trace has been found of them as yet.
