residence of Thomas Müntzer and later the birthplace of Friedrich August Stüler. The Pfafferode Hospital is a large hospital complex within a park, built between 1910 and 1917 at the western edge of the city and is a typical example of the early-20th-century sanatorium architecture in Germany. The Brunnenhaus Popperode is a small Renaissance building in the south-western periphery of Mühlhausen, built in 1614. The well was first mentioned in 1199 as part of the Medieval city's water supply. There are also many architecturally interesting citizens' and patricians' houses within the centre of Mühlhausen, especially along the Steinweg street and at the Untermarkt square. Economy and infrastructure During recent years, the economic situation of the city has improved: the unemployment rate in the Unstrut-Hainich district declined from 21% in 2005 to 10% in 2013 with higher rates in the city than in the bordering rural municipalities. Still, Mühlhausen itself has one of the highest unemployment rates in Thuringia. Agriculture, industry and services Agriculture still plays an important role in the Mühlhausen region today. Approximately 55% of the municipal territory is in agricultural use, mostly for growing cereals and vegetables. The region is a centre of the food industry in Germany, especially in the production of conserves like pickles, sauerkraut, apple sauce, cherries and other fruits and vegetables. A well-known product is the Mühlhäuser Pflaumenmus (Mühlhausian plum jam), which has been produced here since 1908. Production of textiles, machines and electrical engineering were major manufacturing industries in Mühlhausen. Nevertheless, most factories were closed after German reunification in 1990. Since that time, Mühlhausen has had some problems finding a new economic core. Compared to other cities in Thuringia, the economic situation is relatively poor. In 2012, there were only 23 companies with more than 20 workers in the industrial sector, employing a total of 1,800 persons and generating an annual turnover of €314 million. As district capital, Mühlhausen is a regional service hub in retail, health care, cinemas, education, government etc. One of the largest employers is the Bundeswehr, but the closure of the barracks is planned for 2015 with a direct loss of more than 800 jobs in the city. Tourism does not play an important role yet, although the city has many historic sights and the Hainich National Park is only away. In 2012, there were 52,000 overnight visitors staying for a total of 118,000 nights in Mühlhausen. Transport Mühlhausen
