Hietzing () is the 13th municipal District of Vienna (). It is located west of the central districts, west of Meidling. Hietzing is a heavily populated urban area with many residential buildings, but also contains large areas of the Vienna Woods, along with Schönbrunn Palace. Geography The thirteenth district is located at the western end of the city where it borders the Wienerwald. Liesing is to the south, Meidling to the east and Penzing, which was part of Hietzing until 1954, and Rudolfsheim-Fünfhaus, to the north. Most of the northern border is formed by the River Wien. Traditionally, it is subdivided into six parts: Hietzing (northeast), Unter Sankt Veit (northwest), Ober Sankt Veit (west of Unter Sankt Veit), Hacking (northwest of Ober Sankt Veit), Lainz (geographic centre) and Speising (south). Furthermore, the Lainzer Tiergarten, a large park in the Wienerwald populated by boars, and Schönbrunn Palace and the surrounding parks are part of Hietzing. District sections Hietzing was formed from the six former municipalities Hietzing, Unter-St.-Veit, Ober-St.-Veit, Hacking, Lainz and Speising, and is now divided into nine Katastralgemeinden. Six of the Katastralgemeinden broadly align with the former municipal areas. Rosenberg as well as its own Schönbrunn form Katastralgemeinden. Comes to Katastralgemeinde add Auhof, which covers large parts of the district area and essentially Lainzer Tiergarten. Even a small part of Katastralgemeinden Hütteldorf and Unterbaumgarten (14th District) are on Hietzinger area. A breakdown of the district area is also in the census-districts of official statistics in which the census figures of the district municipalities are combined. The eleven census-districts of Hietzing are: Schönbrunn, Hietzing, Auhofstraße, Ober-St.-Veit, Gemeindeberg-Jagdschloßgasse, Lainz, Maxing, Speising, Altersheim Lainz (today: Geriatriezentrum Am Wienerwald), Lainzer Tiergarten and Friedensstadt. Despite partial name matches, the boundaries of the census-districts do not match with those of Katastralgemeinden. Land use The developed area of Hietzing includes only 21.5% (33.3% Vienna-wide) of area of the district, where this is the second lowest value of a municipality of Vienna. The space itself is distributed as 78.7% to 16.5%, for residential areas versus total area of cultural, religious, or sports venues (devoted to public purposes). This relatively high figure is compared to one for a Viennese township as a very low proportion of farmland (4.3% of the area to be developed). Greenspace in Hietzing takes in a share of 71.7%. This is the highest value in Vienna, where the largest area of Lainzer Tiergarten is included.
