Altes Rathaus, Gothic town hall building in Altstadt, Germany

Altes Rathaus was Kiel's town hall until 1911, standing on the southeast side of the Alten Markt in the Altstadt. It was built around 1300, rebuilt in 1596 and 1670, and given its neo-Gothic facade in 1845. Bombing in 1943 destroyed it down to some cellar vaults, which survive.

The building originated in the Middle Ages and underwent several renovations over the centuries as the city's needs evolved. In 1848, it became the gathering place for the March Revolution, where a provisional government met to advance democratic reforms.

The Alte Rathaus housed the provisional government of the duchies of Schleswig and Holstein, which convened there on 24 March 1848 during the March Revolution and the Schleswig-Holstein uprising. A commemorative plaque marking the event was mounted on the building 25 years later, but it did not survive the bombing raids.

The site sits directly at the Old Market in the city center, easily accessible on foot from the main streets. The remaining cellar areas function as part of a restaurant, offering visitors a chance to experience the historic setting while dining or exploring the marketplace.

The new Rathaus built between 1907 and 1911 west of the Old Town was long called the "Neues Rathaus". Since 2008, that name has passed to the former Oberpostdirektion building on Andreas-Gayk-Straße, where parts of the city administration moved. The Old Town hall's successor has thus itself been renamed.
