The Memorial and Education Centre Andreasstraße (German: Gedenk- und Bildungsstätte Andreasstraße), is a museum in Erfurt, Germany, which is housed in a former prison used by the East German Ministry for State Security (Stasi). It is informally known as the Stasi Museum. From 1952 until 1989, over 5000 political prisoners were held on remand and interrogated in the Andreasstraße prison, which was one of 17 Stasi remand prisons in the German Democratic Republic (East Germany). The museum was opened in 2013 as a memorial to repression and resistance in the Thuringia region during the GDR dictatorship. Its permanent exhibitions focus on the experiences of the prison's inmates, the activities of the Stasi, life under the dictatorship, and the Peaceful Revolution which led to German reunification.On 4 December 1989, local citizens occupied the prison and the neighbouring Stasi district headquarters to stop the mass destruction of Stasi files. It was the first of many occupations of Stasi premises throughout the country, and it was a milestone in the Peaceful Revolution. It led to the preservation and opening of Stasi files so that citizens could see what information was held on them and so that the crimes of the Stasi could be exposed.The prison was opened in 1878 and held political prisoners for several different political regimes until 1989. It was closed in 2002.The Memorial and Education Centre Andreasstrasse is managed by the Stiftung Ettersberg.

Petersberg Citadel (German:Zitadelle Petersberg) in Erfurt, central Germany, is one of the largest and best-preserved town fortresses in Europe. The citadel was built on Petersberg hill, in the north-western part of the old town centre from 1665, when Erfurt was governed by the Electorate of Mainz. It is surrounded by over two kilometres of stone walls and is 36 hectares in size.Erfurt has also been ruled by Sweden, Prussia, Napoleon, the German Empire, the Nazis, and post-World War II Soviet occupying forces, and it was part of the German Democratic Republic (East Germany). All of these regimes used Petersberg Citadel and had an influence on its development. The baroque fortress was in military use until 1963. Since German reunification in 1990, the citadel has undergone significant restoration and it is now open to the public as a historic site. Its maze of underground passageways are also open to visitors and the fortress bakery (1832) is again in working order.The fortress is also known by its French name, Citadelle Petersberg, as French troops were stationed there from 1806 to 1814, when Erfurt was under Napoleonic occupation. Napoleon visited Erfurt several times and the citadel was further developed during his rule, although parts of it were damaged in a battle in 1813.The citadel was built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century.The former lower barracks (German:Untere Kaserne) building is now used to house and administer archives of the Stasi Records Agency.The Cyriaksburg Citadel, is a smaller fortress to the south-west of Erfurt city centre, which dates from 1480. It is now the home of the German Horticulture Museum. During the Napoleonic period a hidden trench connecting the two citadels was built. The remains of this connection can still be seen at the Cyriaksburg Citadel today.

The site is almost one hectare (2.5 acres) in size. It was built by Augustinian friars, an order of the Catholic Church. It is most well known as the former home of Martin Luther (1483–1546), the father of the Reformation, who lived there as a friar from 1505 until 1511.About 74 ordained and 70 lay brothers lived at the monastery at its peak in the early 16th century. After the Reformation, from 1525 the monastery church was used by the local Lutheran congregation. The site became the property of Erfurt city council after the last friar died in 1556. It was secularised in 1559, but was later reconsecrated in 1854. It now belongs to the Evangelical Church in Central Germany.Parts of the complex were destroyed in a British air raid in 1945, in which 267 people sheltering on the site were killed. Today the complex has a mixture of medieval and modern buildings. It is now used as a place of worship and as a meeting and conference centre. Music concerts are performed in the church, which has a Walcker organ, built in 1938. It also provides simple accommodation for travellers and for retreats.In February 2016, an application was made to have St. Augustine's Monastery, along with 11 other sites, added to the UNESCO World Heritage Site designated "Luther Sites in Central Germany". Because of their role in the Reformation, all of these sites are considered to "represent one of the most important events in the religious and political history of the world".
