The Museum of Medieval Stockholm was constructed around old monuments excavated in an extensive archaeological dig in the late 1970s. Part of Stockholm's city wall, dating from the early 16th century, was also found. The museum enables visitors to experience medieval Stockholm, with its brick houses and booths, workshops, harbour and gallows. It relates the medieval history of the city from the 1250s to the 1520s. In 2010, to celebrate 800 years since the birth of Birger Jarl, the founder of Stockholm, the museum opened an exhibition with a reconstruction of his face.
The Museum of Medieval Stockholm produces theme exhibitions with a medieval emphasis and arranges lectures, symposia and programmes. It engages in broad educational activities, in which children, youth and schools are a key target group. The museum has a shop that sells books relating to the Middle Ages, and also postcards and jewelry.References:
The Petersberg Citadel is one of the largest extant early-modern citadels in Europe and covers the whole north-western part of the Erfurt city centre. It was built after 1665 on Petersberg hill and was in military use until 1963. It dates from a time when Erfurt was ruled by the Electors of Mainz and is a unique example of the European style of fortress construction. Beneath the citadel is an underground maze of passageways that can be visited on guided tours organised by Erfurt Tourist Office.
The citadel was originally built on the site of a medieval Benedictine Monastery and the earliest parts of the complex date from the 12th century. 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.
