Coat of arms of Augsburg, Germany

Augsburg (UK: /ˈaʊɡzbɜːrɡ/ OWGZ-burg, also US: /ˈɔːɡz-/ AWGZ-; German: [ˈaʊksbʊʁk] ; Swabian German: Ougschburg) is a city in the Bavarian part of Swabia, Germany, around 50 kilometres (31 mi) west of the Bavarian capital Munich. It is a university town and the regional seat of the Regierungsbezirk Swabia with a well preserved Altstadt (historical city centre). Augsburg is an urban district and home to the institutions of the Landkreis Augsburg. It is the third-largest city in Bavaria (after Munich and Nuremberg), with a population of 304,000 and 885,000 in its metropolitan area. After Neuss, Trier, Worms, Cologne and Xanten, Augsburg is one of Germany's oldest cities, founded in 15 BC by the Romans as Augusta Vindelicorum and named after the Roman emperor Augustus. It was a Free Imperial City from 1276 to 1803 and the home of the patrician Fugger and Welser families that dominated European banking in the 16th century. According to Behringer, in the sixteenth century it became "the dominant centre of early capitalism", having benefited from being part of the Kaiserliche Reichspost system as "the location of the most important post office within the Holy Roman Empire" and the city's close connection to Maximilian I. The city played a leading role in the Reformation as the site of the 1530 Augsburg Confession and the 1555 Peace of Augsburg. The Fuggerei, the oldest social housing complex in the world, was founded in 1513 by Jakob Fugger. In 2019, UNESCO recognised the Water Management System of Augsburg as a World Heritage Site because of its unique medieval canals and water towers and its testimony to the development of hydraulic engineering.
