As a result of its dominant geographical site, it is the most important landmark of the town of Porta Westfalica and of northern East Westphalia.
On 15 March 1889, the government of the Province of Westphalia voted with a small majority to erect their Emperor William Monument at the Westphalian Gate (Porta Westfalica).
The prizegiving jury, which also came from Zumbusch awarded first prize to Berlin architect, Bruno Schmitz, whose design was chosen for the monument.
On 18 October 1896 the monument was inaugurated in the presence of Emperor William II and Empress Augusta Victoria during the opening ceremony in which between 15,000 and 20,000 people took part.
[4] From 2013 to 2018 the monument was restored and the area remodelled based on a new visitor concept by architect Peter Bastian from Münster.
There are frequently good views from the Emperor William Monument of the town of Porta Westfalica, the North German Plain and of the Weser Hills on the other side of the gorge.
