The Monument of the Death of Police Officer Sura and Ansen of Karenkou Prefecture (now Hualien County) is located beside the Batongguan Traversing Historic Trail. It is about 100 meters away from the Sasarabi Police Post, and about 1 km away from Dumas Police Post in the east.
The reinforced concrete obelisk-shaped monument was set up by the Governor-General in Taiwan to commemorate two police officers, Sura and Asen, who were killed in an attack on February 17, 1921. The two officers were ordered to patrol and transport supplies to the Dafeng Police Post, and on return to Dumas Police Post in the afternoon, they were killed while patrolling nearby.
