The mysteriousness of Mireuksa Pagoda's architectural technology level.

 The original shape of the pagoda, which was built at Mireuksa Temple more than 1,400 years ago, was probably like this. To the top floor, the height of the tower alone is about 20 meters, including the chalju on the upper wheel, it reaches as much as 28 meters. 28 meters... You can't guess how high it is. Compared to the apartment we live in, you can easily check its height. Only the height of the tower is the height of the 7th floor of the apartment and the height of the 9th floor of the apartment until the end of Chalju. I can feel that it is the largest stone pagoda in the East. As the tower is large, the weight of the stone used is beyond imagination. It's a jade pedestal from the fifth floor. It weighs more than two tons. Then, how did the Baekje people raise hundreds of such heavy stones to a height of 20 meters 1,400 years ago? A huge absence was found during the dismantling work on the fifth floor. How did he put such a big stone up there? It's amazing that old aristocrats put up stones like this. It uses modern construction equipment.The stone used in the stone pagoda is so large and diverse that it is not easy to do it, so what is the weight of the largest stone? Surprisingly, the stone weighed more than two tons. Where is the secret to building not only one or two but thousands of these large stones in a balanced and elaborate manner? The most common way to stack heavy stones in ancient times was to use soil. It is a method of stacking soil to the desired height, rolling stones on it, and removing soil later. Then, did the Mireuksa Temple Pagoda be built in this way? In order to find the clue, the data at the time of the excavation of the Buyeo Cultural Heritage Research Institute, which was in charge of excavation, began to be carefully reviewed. As a result, a cornerstone of a certain shape was found in the tower. It was not only in the east tower but also in the west tower. As an H-shaped cornerstone of the alphabet, a cornerstone of the same shape was found in front of the south of the East-West Tower. However, since it has no origin, no one paid attention at first. "I found an H-shape in the east pagoda, I just covered it, but I found another tower..." There is something..." All of the east and west pagodas were found on the south side of the stylobate. Professor Bae Byung-sun, an architecture expert, argues that the foundation was a kind of "craver" because he visited the Korean Traditional Culture School to find out exactly the identity of the foundation since the tower was built. Through the arrangement of the cornerstones, the specific shape of the crane used at the time was estimated. It is explained that the stone of the stone pagoda would have been raised by connecting the two poles and attaching a pulley to the top, so would there have been a pulley more than 1,400 years ago? The Daegu Museum has a valuable relic confirming that there was a pulley at that time, Yongdubodang Shrine in the Unified Silla Period found in Punggi, Gyeongsangbuk-do. The dragon has a pulley in its mouth, the most rudimentary crane shape. Yongdu was raised at the entrance of the temple and at the end of the flagpole, and the flag of the temple was raised through a pulley. Another place found a pulley used. The inside of Anak No. 3 and Anak No. 3 in Hwanghae-do Island is filled with colorful murals that give a glimpse into the beauty of Goguryeo art. However, there is a prominent painting on one side of the mural depicting Goguryeo's life. It is also a well. This well is also a device for raising water in the picture. You can see that you are using a pulley right away. Then, what shape is the crane used in Mireuksa Pagoda? Suwon Hwaseong Fortress was built during King Jeongjo's reign, and it is famous for its use of various types of cranes when constructing castles. In the orbit of Hwaseong Fortress, cranes used to build Hwaseong Fortress in Suwon are detailed with pictures. In particular, Nokro is a type of crane that uses pulleys to simply lift heavy things up and is known to have been used most often in Joseon Dynasty architecture, but surprisingly, the floor structure of Nokro almost coincides with the H-shaped cornerstone found in Mireuksa Pagoda. Professor Bae Byung-sun argues that this very form of crane was used to build Mireuksatap Pagoda. It is a crane of the Baekje period restored through the H-shaped cornerstone. However, a total of four wooden remains were found about 6 meters away from the H-shaped cornerstone. What is this phrase? This crane was a developmental type of crane that moved left and right as well as a function of lifting stones up. In other words, Baekje's crane, restored through the H-shaped cornerstone, is a form of crane that is one step ahead of the Nokg-ro of the Joseon Dynasty. Now, this is the crane used by the Baekje people. It's amazing that there was already a crane like this 1,400 years ago, similar to the current construction equipment. Mireuksatap Pagoda was a symbolic tower that contained Baekje's science and technology as a whole.
