History+
King Ludwig I of Bavaria commissioned the construction of the Befreiungshalle to honor the triumphs of the Wars of Liberation between 1813 and 1815. Construction began in 1842 under the direction of Friedrich von Gärtner, who drew inspiration from ancient and Christian central building concepts. At the laying of the foundation stone on October 19, a choral song with a text composed by the king himself was performed.
