银阁寺

银 = 艮 + 钅 : Maud Younger spotted a large silver sphere hanging above the entrance to the encampment. She wants to have it and repeatedly throws a golden harpoon at it; to retract the harpoon she uses a chewing gum which she attached to the harpoon, so that it expands to a long rope as she throws the golden harpoon at the silver sphere.

阁 = 各 + 门 : Guy Fawkes (g) has a hidden two-storied pavilion (阁) in the elevator's kitchen (e2). Of course he built it underground, and the entrance is a trap door (门) with a big star (各) on it.

寺 = 土 + 寸 : Socrates (s) built a Buddhist temple (寺) in the space station's bathroom (Ø4). To protect it from being destroyed while floating around in zero gravity, he built a protective frame made out of mud (土) around it. After finishing it he inspects it and thinks "thumbs up" (寸), because he is proud of his work.
