The medieval town of Duderstadt, in the Eichsfeld to the southwest of the Harz, is huddled within the 3km/2mi long circuit of its walls. It has about 500 half-timbered houses.
In the Duderstadt Untermarkt is the Protestant parish church of St Servatius (or Unterkirche; 15th-16th C.), with an interior partly decorated in Art Nouveau style.
The central feature of Duderstadt is the Obermarkt, with the Town Hall (13th-16th C.). This is an imposing half-timbered building with three small towers and sandstone arcades on the ground and first floors (historical exhibition; carillon).
