古蹟

古 = 十 + 口 : Mnemonic symbol: at least on German maps, this character actually resembles a cloister.

Oh no! Gitta Giraffe (gu) found that the golden cross (十) broke off of the cloister (古) in the space station's living room (Ø3)! She skewers a mandarin (口) on top of the cloister so that she can skewer the broken off cross back on to fix it.

迹 = 亦 + 辶 : Joan of Arc (ji) is caring for the also-ran (亦) after she finished a marathon in the space station's bathroom (Ø4). The also-ran was wearing gladiator sandals (辶) but already after half of the race they were worn through, and Joan of Arc can see the footprints (迹) the also-ran left with her bare feet when she came in.
