Paju Historical Site Related to Yi I is dedicated to a great scholar of the mid-Joseon dynasty. He was born to Lee Wonsu and Shin Saimdang in 1536. He passed Saengwonsi, a type of preliminary exam in 1564 (the 9th year of King Myeongjong), and another 9 exams so he was called Gudo Jangwongong. He served in key positions. He is thought to be one of the top two scholars along with Yi Hwang.
