The Gothic Rathaus (City Hall) in Münster is where the Peace of Westphalia was signed in 1648 — ending the Thirty Years' War and establishing the modern concept of state sovereignty. The restored Peace Hall (Friedenssaal) contains period furnishings and portraits of the negotiators.
The Rathaus (city hall) of Münster was built in Gothic style in the 14th century as the seat of municipal government for the free imperial city, its stepped gable facade on the Prinzipalmarkt remaining one of the most recognisable civic buildings in Westphalia. Its historical significance rests on the Friedenssaal, or Peace Hall, where representatives of the Holy Roman Empire, Spain, France, Sweden, and the Dutch Republic concluded negotiations culminating in the Peace of Westphalia, signed in 1648 to end the Thirty Years' War, a conflict that had devastated Central Europe for three decades. The treaties signed partly in Münster and partly in nearby Osnabrück are widely credited by historians and political scientists with establishing the modern concept of state sovereignty and non-interference, principles still referenced today as the foundation of the international system of nation-states, sometimes called the Westphalian system. The Friedenssaal itself preserves oak panelling, portraits of the negotiating delegates and European rulers of the period, and furnishings evoking the room's appearance during the 1648 negotiations, though the room and much of the building's original medieval fabric required painstaking reconstruction after the Rathaus was severely damaged by Allied bombing in 1945. Restoration teams worked from historical drawings and surviving fragments to rebuild the facade and interior to their pre-war appearance, a project completed over subsequent decades that allows visitors today to stand in a room widely regarded as one of the birthplaces of modern international diplomacy. A small museum adjoining the hall displays original documents, coins, and other memorabilia connected to the peace negotiations.
