Floridsdorf
Floridsdorf is the 21st district of Vienna, Austria. Located north of the Danube, it comprises former villages such as Floridsdorf, Donaufeld, Jedlesee, Leopoldau, Stammersdorf, Strebersdorf, and Groß-Jedlersdorf. With a population of over 189,000 in 2025, it is Vienna’s third most populous district and one of the fastest growing. Floridsdorf is known for its blend of urban infrastructure and green spaces, including vineyards, parks, and historical architecture
Geography
Floridsdorf lies in the northeastern part of Vienna, on the left bank of the Danube. It is bordered to the south and west by the Danube River, to the east by the 22nd District, and to the north by Lower Austria. The terrain is diverse: the northwest includes the gentle foothills of the Bisamberg, while the southeast is a flat plain formed by the Danube’s old floodplain. The Danube itself, along with the parallel New Danube channel and part of the Danube Island, forms Floridsdorf’s southern boundary. The northern segment of the Old Danube also flows through the district, providing popular waterfront recreation. In 1870–1875, the Danube Regulation tamed the river’s floods and created new land for settlement in Floridsdorf’s southern plains.The district contains abundant green areas and parks. Vineyards and agricultural fields still characterize the northern localities of Stammersdorf and Strebersdorf, where the slopes of the Bisamberg are covered with vineyards and protected meadows. Remnants of riparian forest survive in the Schwarze Lackenau wetlands and the Floridsdorfer Aupark, recalling the Danube’s original floodplain ecosystem. The Marchfeldkanal – a canal completed in 1992 – cuts across Floridsdorf, its banks forming a green corridor and feeding ponds that host rare flora and fauna. Despite urbanization, pockets of vegetable farms and garden allotments remain in areas like Donaufeld, though these open spaces have been steadily receding with new housing projects.
Subdivisions
Administratively, Floridsdorf is divided into localities corresponding to the former villages and cadastral communities. The seven core subdivisions are Floridsdorf, Donaufeld, Großjedlersdorf, Jedlesee, Leopoldau, Stammersdorf, and Strebersdorf. In addition, Floridsdorf includes small parts of Kagran and Kaisermühlen that border the 22nd District. Each quarter has a distinct character: for example, Floridsdorf center is a busy urban node and district administrative center, whereas Stammersdorf retains a village atmosphere famous for its Heuriger wine taverns and vineyards.For statistical purposes, the district is further divided into 28 Zählbezirke. These carry names often derived from local neighborhoods or landmarks – e.g., Großfeldsiedlung, Siemensstraße, Jedlersdorf, or Autokader. The census districts largely align with the traditional sub-districts but with some differences in borders. They reflect Floridsdorf’s development, from the old village cores to 20th-century settlements and industrial zones.
Public transportation in Floridsdorf is very common for example: Underground Lines, Buses
Parks and Natural Areas
Floridsdorf offers extensive green and recreational spaces. The Danube Island, a long artificial island created as part of flood control, spans the district’s southern edge and provides parks, beaches, and cycling paths. On the island, the Japanese Cherry Tree Park near the Jedleseer Brücke footbridge is notable for its annual cherry blossom festival. The Old Danube’s shores host lidos and boating areas popular in summer. In the north, the slopes of the Bisamberg and the adjacent nature reserve are crisscrossed with hiking trails and dotted with heuriger wine gardens, blending nature with Vienna’s wine culture. A new central park, the Gaswerk-Park, is being created as part of the “Neu Leopoldau” development on the site of the old gas works, adding 8,500 m² of green space in the heart of a new residential quarter.History
I. Prehistory and Antiquity
Human settlement in the Floridsdorf area dates back to prehistoric times. Archaeological finds indicate that Neolithic people lived here, as evidenced by stone axes and pottery fragments unearthed in the district. In the Leopoldau area, weapons and jewellery from the Bronze Age have been discovered, indicating continuous settlement into antiquity.1. Celtic and Roman Period
By around 500 BC, Celtic tribes inhabited the region, though their influence waned with the arrival of the Romans. During the Roman era, the area north of the Danube formed a border zone between the Roman Empire and Germanic tribes, often witnessing skirmishes and serving as a no-man’s-land.2. Early Migrations and Bavarian Settlement
After the end of Roman rule in the 5th century, waves of migrating peoples passed through or settled in the area, including the Lombards, Avars, and Slavs. The Avars were defeated by Charlemagne around 800, after which Bavarian settlers entered the region.3. Babenberg Rule and First Records
By the late 9th and 10th centuries, the territory came under Magyar raids until their defeat in 955. Under the Babenberg rule of eastern Austria, the area began to be resettled and organized. The earliest recorded settlement in what is now Floridsdorf is Jedlesee, which is mentioned in a 1014 deed issued by Emperor Henry II for the Bishop of Passau.II. Early and High Middle Ages
Throughout the Middle Ages, the Floridsdorf area was under various lordships as part of the region northeast of Vienna. By the 12th and 13th centuries, villages like Jedlersdorf and Jedlesee existed along the Danube’s old channels.1. Flooding and Ferry Crossings
The territory was frequently affected by flooding from the unregulated Danube, which often altered property boundaries and made agriculture challenging. For a long period, crossing the Danube from this area was only possible by ferry. The strategic importance of the location grew over time: a small ferry settlement at Jedlesee prospered by operating a boat service across the “Schwarze Lacke” for travelers heading toward Vienna.2. Emergence of Am Spitz and First Bridges
By the Late Middle Ages, major overland trade routes from Vienna into Bohemia and Moravia converged at a point known as “Am Spitz.” Around 1500, the first permanent bridge was constructed, followed by the Kuhbrückl. These facilitated growth and led to a roadside settlement called “Jedlersdorf am Spitz.”III. Formation of Floridsdorf and 19th-Century Growth
1. Naming and Early Community Organization
In 1786, Floridus Leeb granted land east of Am Spitz to settlers, and the area was named “Floridsdorf” in his honor.2. Industrialization and Railways
Floridsdorf transformed during the 19th century with the arrival of the railway in 1837, becoming Austria’s first railway station north of the Danube. The development of additional railways and factories, including the locomotive factory, turned it into an industrial hub.3. Expansion and Status as a Town
By 1894, Floridsdorf merged with Donaufeld, Jedlesee, and Neu-Jedlersdorf, forming a municipality of over 30,000 people. It was officially recognized as a town, and a Town Hall was built between 1901 and 1903.IV. Incorporation into Vienna (1905)
Floridsdorf was incorporated into Vienna as the 21st district effective 1 January 1905. This followed political negotiations and a town council petition. The town hall became the district’s Magistratisches Bezirksamt.V. Floridsdorf during World War II
1. Territorial Changes and Persecution
In 1938, Floridsdorf lost eastern parts to the new 22nd District and gained Stammersdorf. The Floridsdorf synagogue was destroyed in 1938, and a subcamp of Mauthausen was established in Jedlesee in 1944.2. Bombing and Soviet Occupation
Floridsdorf was bombed by the Allies and saw heavy fighting in April 1945. The Floridsdorfer Brücke and the Bisamberg transmitter were destroyed. Soviet forces occupied the district on 15 April 1945.VI. Post-war Floridsdorf
1. Border Adjustments and Housing
In 1954, district boundaries were finalized. Stammersdorf became part of Floridsdorf, while areas like Kagran went to the 22nd District. Housing projects such as Schlingerhof, Karl-Seitz-Hof, and Großfeldsiedlung supported post-war growth.2. Infrastructure and Transport
Floridsdorf gained major transport improvements: S-Bahn, Nordbrücke, Brigittenauer Brücke, and U6 metro. The Veterinary University relocated to the district.VII. Floridsdorf in the 21st Century
Floridsdorf continues to grow with developments in Donaufeld and Neu-Stammersdorf. The U1 line was extended in 2006, and Klinik Floridsdorf opened in 2019. The district balances urbanization with village character and recreational areas like Donauinsel and the Wasserpark.Demographics
Population growth
Floridsdorf’s population has shown steady long-term growth with periods of rapid increase. In 1869, the area had just over 12,000 inhabitants. Industrialization and the 1905 incorporation into Vienna spurred a population boom: by 1910 Floridsdorf reached 62,154 residents – more than five times the 1869 figure. After World War I, growth slowed as the district remained less densely built-up than inner-city districts. The Nazi-era split in 1938 reduced Floridsdorf’s population, and WWII caused a temporary decline. By 1951, the district was home to around 85,000 people. Thereafter, new housing projects led to continuous increases. Floridsdorf’s population crossed 100,000 in the 1960s and 130,000 by the late 20th century.Since the 1990s, Floridsdorf has experienced another surge of construction and influx of residents. Between 2001 and 2011, the population jumped from about 128,000 to 144,000. This trend accelerated in the 2010s with large developments. As of 1 January 2025, Floridsdorf’s population is 189,580, making it the third most populous Vienna district. The district grew by 50% in the first 25 years of the 21st century, an increase of over 63,000 people – one of the highest growth rates in the city. City forecasts project Floridsdorf will exceed 200,000 inhabitants before 2030. Despite this growth, population density remains moderate by Vienna standards due to the district’s large open areas.
