Mariahilf (; Central Bavarian: Mariahüf) is the 6th municipal district of Vienna, Austria (). It is near the center of Vienna and was established as a district in 1850. Mariahilf is a heavily populated urban area with many residential buildings. It has a population of 31,621 (as of 2016-01-01) within an area of . Location Mariahilf is located southwest of Vienna's centre (1st district). In the north, Mariahilfer Straße, Vienna's most important shopping street, is its border with Neubau, in the south, the valley of the Vienna River, in the west, the Gürtel beltway. It consists of the five neighbourhoods (historical Vorstädte, i.e. towns): Mariahilf, Gumpendorf, Windmühle, Magdalenengrund and Laimgrube. History First settlements around the Roman roads of the area developed around the year 1000. In 1428, the name Im Schöff is mentioned for the first time, but this name was lost when the copy of a sacral painting from Passau was installed in a chapel of the graveyard, which came to be known as Mariahilf ("Mary's help"). More intensive settlement started only after the Second Turkish Siege of Vienna in 1683. The area was of some importance because the road to Schönbrunn Palace led through it. Gumpendorf was mentioned in 1130 for the first time and developed from a Roman watchtower. It was subject to various feudal lords and was sold to the municipality of Vienna in 1798. Magdalenengrund was originally known as Im Saugraben an der Wien auf der Gstätten ("In the sow pit on the Wien on the meadow") and consisted only of vineyards. In 1698, some plots were released for construction. The Laimgrube (clay pit) is probably the oldest part of Mariahilf. It was mentioned in 1291 for the first time, but has existed already since the 11th century. Its name is derived from the clay soil, which was used to produce bricks. Windmühle (windmill) developed from a feudal holding used by various monastic orders. In 1529 it was destroyed during the First Turkish Siege. Emperor Ferdinand I had the ownership transferred to Johann Francolin, subject to the condition that he should build windmills there. However, he had only one mill built. On March 6, 1850, the five Vorstädte of Gumpendorf, Mariahilf, Windmühle, Magdalenengrund and Laimgrube became part of Vienna as the Fifth District, Mariahilf. When Wieden was split into two districts in 1861, it became the 6th District. In 1862, some areas north of Mariahilfer
