Korneuburg

Korneuburg began as a market on the left bank of the Danube opposite Klosterneuburg. After repeated floods the settlement moved inland around 1200; about 1298 it became separate from its neighbour. Its prosperity rested on river trade in salt, wine and grain. A privilege of 1327 made Korneuburg the sole staple port on the left bank between Krems and Vienna, and Alpine salt passed through it to the hinterland.

The town's Jewish community built a synagogue in the fourteenth century, but was expelled during the persecution of 1420. The building later served as a grain store and horse-driven mill. Korneuburg's walls were strengthened in the 1420s, yet the town was badly damaged when Hungarian forces under Matthias Corvinus besieged and captured it. During the Thirty Years' War, imperial troops retook it from the Swedes in 1646; the siege damaged or destroyed two thirds of its houses.
