Maybe it's Korea's Shamanist traditions that place changseung (totems) on guard at the entrances
to many towns and important places. The anatomically correct characters above watch over Seongyojong,
the House of 100 Rooms. I guess part of their job is to make sure that no one gets in without paying
the 5000 won (about US$5) admission fee.
That tariff shows you where in inflation is going in Korea, by the way. Back in 2000, each of us paid
just 1000 won to get in.
