Karlstadt is a town in the Main-Spessart in the Regierungsbezirk of Lower Franconia (Unterfranken) in Bavaria, Germany. It is the administrative centre of Main-Spessart (Kreisstadt), and has a population of around 15,000. Geography Karlstadt lies on the River Main in the district (Landkreis) of Main-Spessart, roughly 25 km north of the city of Würzburg. It belongs to the Main-Franconian wine-growing region. The town itself is located on the right bank of the river, but the municipal territory extends to the left bank. Since the amalgamations in 1978, Karlstadt's Stadtteile have been Gambach, Heßlar, Karlburg, Klein Laudenbach, Laudenbach, Mühlbach, Rohrbach, Stadelhofen, Stetten, and Wiesenfeld. History From the late 6th to the mid-13th century, the settlement of Karlburg with its monastery and harbor was located on the west bank of the Main. It grew up around the Karlsburg, a castle perched high over the community, that was destroyed in the German Peasants' War in 1525. In 1202, Karlstadt itself was founded by Konrad von Querfurt, Bishop of Würzburg. The town was methodically laid out with a nearly rectangular plan to defend Würzburg territory against the Counts of Rieneck. The plan is still well preserved today. The streets in the old town are laid out much like a chessboard, but for military reasons they are not quite straight. In 1225, Karlstadt had its first documentary mention. In 1236, the castle and the village of Karlburg were destroyed in the Rieneck Feud. In 1244, winegrowing in Karlstadt was mentioned for the first time. From 1277 comes the earliest evidence of the town seal. In 1304, the town fortifications were finished. The parish of Karlstadt was first named in 1339. In 1369 a hospital was founded. Between 1370 and 1515, remodelling work was being done on the first, Romanesque parish church to turn it into a Gothic hall church. About 1400, Karlstadt became for a short time the seat of an episcopal mint. The former Oberamt of the Princely Electorate (Hochstift) of Würzburg was, after Secularization, in Bavaria's favour, passed in 1805 to Grand Duke Ferdinando III of Tuscany to form the Grand Duchy of Würzburg, and passed with this to the Kingdom of Bavaria. The Jewish residents of the town had a synagogue as early as the Middle Ages. The town's synagogue was destroyed on Kristallnacht (the Night of Broken Glass, 9 November 1938) by Nazi SA men, SS, and Hitler Youth, as well
