A circular, single-story building with walls constructed from rounded fieldstones stands in a wooded area in Mshiri, Tanzania. The conical roof is made of weathered, corrugated metal, exhibiting moss growth. Three rectangular, wood-framed windows with vertical security bars are visible. The building is encircled by a wire mesh fence with barbed wire. Several tall evergreen trees surround the structure. A low, moss-covered stone wall defines the edge of a reddish-brown dirt path in the foreground. No individuals are present. The sky is overcast.
