Dourdan is a historic town with a magnificent church called the Église de Saint-Germain l'Auxerrois. Renamed the "Temple of Victorious Reason" during the Revolution, the church now contains a statue that bears a striking resemblance to Darth Vader (known as Dark Vador in France).

Daniel takes us inside the castle of Dourdan, with its belfry, arrow loops, and many fortifications. This castle has a somewhat unusual history: find out why its roof was knocked off and why it was pretty much impregnable.
