Herlufsholm Church is Denmark's broadest single nave church and was the monastery church for the Woodland Monastery of the Benedictine Order. The church dates back to 1135. When Herluf Trolle and his wife Birgitte Goeye acquired the monastery in 1560, the church was renamed Herlufsholm and it became the area's parish church. In the chapel under the choir, Herluf Trolle and Birgitte Goeye lay buried. They are also remembered in an epitaph. In the northern arm of the choir there is a sepulchral monument to Marcus Goeye with an epitaph by Thomas Kingo. The jewel of the church is an ivory crucifix, a 75cm high and carved from a single tusk - one of Denmark's finest works of art.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.
