이곳 일대는 원래 용강산을 굽어보던 함벽정 터로 이곳에서 성직자들이 참수된 한강가의 새남터와 많은 천주교도들이 피를 흘린 당고개가 가까이 바라보인다 하여 고종 23년(1886) 천주교회에서 구입하였다.
This area was originally purchased from the Catholic Church in King Gojong's 23rd year (1886), because you can see Hambyeokjeong Pavilion site, which overlook Yonggang Mountain and is where the priests were beheaded, and the Senamteo Martyrium, where many Catholics were beheaded and the Danggoga where many Catholics shed blood, can be seen.
