Oak vs Salzburg

Informations

An oak is a tree or shrub in the genus Quercus (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus (stone oaks), as well as in those of unrelated species such as Grevillea robusta (silky oaks) and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.

Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small female flowers, meaning that the trees are monoecious. The fruit is a nut called an acorn or oak nut borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on their species. The acorns and leaves contain tannic acid, which helps to guard from fungi and insects. The live oaks are distinguished for being evergreen, but are not actually a distinct group and instead are dispersed across the genus.

Salzburg (Austrian German: [ˈsaltsbʊʁk]; German: [ˈzaltsbʊʁk] (listen); literally "Salt Fortress"; Bavarian: Soizbuag) is the capital city of the State of Salzburg and fourth-largest city in Austria. In 2020, it had a population of 156,872.The town is located on the site of the former Roman settlement of Iuvavum. Salzburg was founded as an episcopal see in 696 and became a seat of the archbishop in 798. Its main sources of income were salt extraction and trade and, at times, gold mining. The fortress of Hohensalzburg, one of the largest medieval fortresses in Europe, dates from the 11th century. In the 17th century, Salzburg became a centre of the Counter-Reformation, where monasteries and numerous Baroque churches were built.

Salzburg's historic centre (German: Altstadt) is thus renowned for its Baroque architecture and is one of the best-preserved city centres north of the Alps, with 27 churches. It was listed as a UNESCO World Heritage Site in 1996. The city has three universities and a large population of students. Tourists also visit Salzburg to tour the historic centre and the scenic Alpine surroundings. Salzburg was the birthplace of the 18th-century composer Wolfgang Amadeus Mozart. Because of its history, culture, and attractions, Salzburg has been labeled Austria's "most inspiring city."
