Special traditional landmarks throughout South Korea remind the people of days past. One such landmark is the
Namdaemun (South Gate). Walls used to surround Seoul, the capital, with four compass gates; Namdaemun led straight to the
Deoksu Palace. Built in 1398, it still stands at in intersection in the bustling city of Seoul to remind the people of tradition.
A landmark that reminds Koreans of a glorious moment in history is the Admiral Yi Sun Shin Statue located in Seoul as well.
Yi Sun Shin was a naval commander that invented “turtle-ships”—the first iron-clad ships in the world. A
Korean fleet of only twelve turtle-ships defeated 133 Japanese ships, preventing invasion at that time. Asia’s first
night sky observatory, Chomsongdae, is also a big attraction in South Korea. It was constructed in 632 A.D. and is one of
the world’s oldest observatories. There are thirty layers from bottom to top, one for each day of the month, twelve
base stones, one for each month of the year, and built with 366 stones, one for each day of the year (so was believed by the
people in that period).
