Jikji, Selected Teachings of Buddhist Sages and Seon Masters, the earliest known book printed with movable metal type, 1377. Bibliothèque Nationale de Paris.
One of the best known artifacts of Korea's history of science and technology is the Cheomseongdae (첨성대, 瞻星臺), a 9.4-meter high observatory built in 634.
The earliest known surviving Korean example of woodblock printing is the Mugujeonggwang Great Dharani Sutra.^[190] It is believed to have been printed in Korea in 750–51, which if correct, would make it older than the Diamond Sutra.
During the Goryeo Dynasty, metal movable type printing was invented by Choe Yun-ui in 1234.^{[191][6][192][193][9][4]} This invention made printing easier, more efficient and also increased literacy, which observed by Chinese visitors was seen to be so important where it was considered to be shameful to not be able to read.^[194] The Mongol Empire later adopted Korea's movable type printing and spread as far as Central Asia. There is conjecture as to whether or not Choe's invention had any influence on later printing inventions such as Gutenberg's Printing press.^[195] When the Mongols invaded Europe they inadvertently introduced different kinds of Asian technology.^{[citation needed]}
During the Joseon period, the Turtle Ship was invented, which were covered by a wooden deck and iron with thorns,^{[196][197][198]} as well as other weapons such as the bigyeokjincheolloe cannon (비격진천뢰, 飛擊震天雷) and the hwacha.
The Korean alphabet hangul was also invented during this time by King Sejong the Great.
