Not far beyond the “secret gate” is the March First Independence (Movement) Memorial Tower. It commemorates the nationwide protest against the Japanese colonial government that took place in 1919 (on March 1st, of course).
I really liked this monument, but the small clearing in which it was located made it difficult to capture the whole thing in one photo. It has two distinct design elements: the wings and the tower. This photo shows the wings, which are inset with brass relief sculptures depicting the protests. The scene on the left shows students, women, and even an old man in traditional clothing (on right-hand side), showing how widespread the movement was in Korean society.
The small stone table in front of the monument is an altar for offerings.
