The Emperor William Monument, near the town of Porta Westfalica in the North Rhine-Westphalian county of Minden-Lübbecke, is a colossal monument above the Weser gorge of Porta Westfalica, the "Gateway to Westphalia". It was erected to honour the first German Emperor, William I (1797–1888), by the then Prussian Province of Westphalia between 1892 and 1896 and emerged against the background of a rising German national identity. The monument, which is around 88 metres (289 ft) high, is classified as one of Germany's national monuments.

Minden is a middle-sized town in the very north-east of North Rhine-Westphalia, Germany, the largest town in population between Bielefeld and Hanover. It is the capital of the district (Kreis) of Minden-Lübbecke, which is part of the region of Detmold. The town extends along both sides of the River Weser, and is crossed by the Mittelland Canal, which is led over the river on the Minden Aqueduct.
