Since 2003, OURs has promoted a series of art-related activities in Treasure Hill, including one planned by Finnish artist Marco Casagrande. After looking over the remains of some of the village's demolished buildings, Casagrande decided to hand-build a wooden stairway over them to make it easier for people who lived upslope to get to and from their homes.
2003 年以來，OURS 在寶藏巖推動了一系列的藝術行動計畫。其中芬蘭藝術家 Marco Casagrande 在觀察過去被拆毀的房舍遺跡後，決定以手工方式在廢墟立面上興建木階梯，讓山坡上的住戶得以方便進出。
