Altranstädt Castle is located in the heart of the rural idyll of the village of Großlehna. Since the summer of 2008, bridal couples have been saying “I do” in a place of peace here. European history was once written in the rooms. The Great Northern War (1700 - 1721) arose as a result of Sweden's hegemonic efforts in the Baltic region, against which Denmark, Saxony-Poland and Russia allied in 1697. During this time the castle came under Swedish occupation. From 1706 to 1707 it was the headquarters and seat of government of King Charles XII of Sweden. On September 24, 1706, the then victorious King of Sweden and Augustus the Strong (Elector of Saxony and King of Poland Augustus II) concluded the "Altranstadt Peace" in Altranstädt Castle. Accordingly, August the Strong renounced the Polish crown. The so-called “Peace Room” in which the treaty was negotiated and signed still bears witness to this today. The following year, on August 22, Charles XII. and the Imperial Austrian special envoy Johan Wenzel Graf Wratislav von Mitrowitz the Altranstadt Convention. She secured i.a. freedom of religion for the Silesian Protestants.
