Porta Westfalica
The Emperor William Monument is located at the extreme eastern end of the range of the Wiehen Hills on the eastern slopes of the Wittekindsberg ( above sea level (NHN)). It towers above the great gorge of Porta Westfalica, through which the River Weser flows between the Wiehen Hills in the west and the Weser Hills in the east and between the towns of Porta Westfalica in the south and Minden in the north. It is here that the Weser breaks out of the German Central Uplands and winds across the North German Plain. The site used to be on the eastern border of the old Province of Westphalia with Porta Westfalica. The monument lies within the municipality of Barkhausen in the borough of Porta Westfalica.
