Floridsdorf (; Central Bavarian: Fluridsduaf) is the 21st district of Vienna (), located in the northern part of the city and comprising seven formerly independent communities: Floridsdorf, Donaufeld, Greater Jedlersdorf, Jedlesee, Leopoldau, Stammersdorf, and Strebersdorf. History Prehistory Settlements were already present during the New Stone Age (4000 to 2000 BC). Stone axes and potsherds unearthed from that time indicate that the first settlers in the area were hunters. In the vicinity of Leopoldau, bronze weapons and jewelry provide evidence of subsequent settlement. Several of these items are now in the District Museum. Early history Around 500 BC, Celts entered the territory of present-day Floridsdorf, losing ground to the Romans as their empire expanded. The territory became a no-man's-land, or buffer zone, between the Romans and teutonic tribes, during a period when repeated battles were fought between the two peoples. After the end of Roman rule, the territory attracted Lombards, Pannonian Avars, and Slavs. The Avars were later defeated by Charlemagne. Middle Ages The Magyars had conquered the Pannonian Basin (present-day Hungary) by the end of the ninth century, and launched a number of plundering raids both westward and southward. The westward raids were stopped only with the Magyar defeat at the Battle of Lechfeld of 955, which led to a new political order in Western Europe centered on the Holy Roman Empire. Around 1000 AD, the Babenberg ruled in the area that is now modern Vienna. In 1014 came the first written mention of what today is Floridsdorf Jedlesee, then called Outcinesse (Sea of Uz). For a long time, the Danube could be crossed only by ferry. In the year 1500, the first bridge was built. At the site of today's Floridsdorfer Haupstrasse, near the water park, the first wooden bridge (Tabor Bridge) was built. Another bridge, the Kuhbrückl, crossed a small arm of the Danube. At the fork of the main road to Bohemia and Moravia, the new settlement of Floridsdorf came into being. Modern period Floridsdorf was first called "Am Spitz" and was later assigned to the Klosterneuburg Monastery. In 1786 Floridus Leeb, abbot of the monastery, transferred 26 properties to settler families. Through industrialization, Floridsdorf, originally an agricultural area, changed in a short time, so that on 8 May 1894 with the villages Donaufeld, Jedlesee and New Jedlersdorf, Floridsdorf was augmented to form a larger community. The steam tramway and the Northwest Railway have also contributed to
