Sct. Jørgensbjerg church is situated on top of Sct. Jørgensbjerg hill with a lovely view of Roskilde Fjord. The oldest parts of the travertine church are the choir and the nave from the 11th century. It is the oldest preserved stone building in Denmark.
The slender billets at the corners and in the middle of the nave are quite unique. Such billets are only found in wooden churches, hence its name "a fossilized wooden church". There are many interesting details in the interior of the church. A model of a medieval merchant vessel, a so-called "kogge", has been engraved in the wall.
The church is closed during religious ceremonies.
