100 Days My Prince | Yongin Daejanggeum Park — The Court That Never Left the Lot

Yongin keeps a whole dynasty on a hillside and sells tickets to walk it.

Daejanggeum Park, at 25 Yongcheon drama-gil in Baegam-myeon, is MBC's outdoor historical lot, once branded Dramia. The usable sets cover palace halls, a market street, government offices, and houses from several centuries. VisitKorea still lists the hours and the costume rooms. The coordinates sit at 37.1212, 127.3371, far enough from Seoul that the horizon stays rural.

100 Days My Prince shot court interiors and official processions on this ground. The palace in the story is a political machine. The palace you can visit is timber, plaster, and painted brackets arranged so a camera can move from throne hall to side court without a modern window. When Kim Cha-eon tightens the conspiracy and the Crown Princess holds her seat, those rooms were here, not in Gyeongbokgung.

The park is open most days except Seollal. Admission is higher than a fortress village because the buildings exist only as a set. That is the point. You are walking the architecture the series built its palace plot on.

Stand at the market street first, then walk uphill toward the larger halls. The slope does the same work the drama did: it separates common noise from the rooms where a name can get a man killed.
