Der graves i Roskilde. I kannikernes gamle by og man finder skeletter og mønter, der rykker ved historien. Det hele foregår her og nu i sommer, hvor Piet van Deurs rejser rundt med Danmarkshistorier, og denne gang er i den gamle domkirkeby. En gammel drøm er gået i opfyldelse for Michael Andersen da han fik lov at grave bag den gamle kirke. Michael Andersen fortæller om Hertug Christoffer, der ligger i sarkofagen i domkirken. Død i kamp, og hvis signet man har fundet i jorden bag domkirken. Og vi skal med i en ruin under Stender torvet.
Roskilde is being dug. In the old city of the canons, skeletons and coins that change history are found. It's happening this summer, that Piet van Deurs is travelling with the show Denmarkstoris, and this time he is in the old cathedral city. An old dream has come true for Michael Andersen, when he was allowed to dig behind the old church. Michael Andersen tells of Duke Christoffer, who lies in the sarcophagus in the cathedral. Died in batle, and whose signet has been found in the dirt behind the cathedral. We also descen to a ruin beneath the estates square.
