St Martin's church is an 18th-century listed building and Catholic parish church in Junglinster, Grevenmacher. It contains artworks and monuments from the older parish church that the building replaced. The oldest monuments commemorate members of the noble d'Orley family, to whom the Renaissance artist Bernard van Orley was related.
The parish has existed since medieval times, but by 1688 the original church was in a state of disrepair, and litigation about who was responsible for upkeep delayed renovation. In January 1744, Johannes Otto Borrigs became parish priest. In the 1750s Borrigs laid out a walled garden around the presbytery, and in 1762 had a new presbytery built in the style of a manor house. The contrast between the new presbytery and the dilapidation of the church itself led to pressure to build a new church. Agreement was reached in 1771, and the new building was erected in 1772–1773, to plans attributed to Paul Mungenast (1735–1797), master of works to the Abbey of Echternach. The inspiration for the design was the Basilica of St. Paulinus, Trier.
The building was consecrated on 24 July 1774 by the auxiliary bishop, Johann Nikolaus von Hontheim. The murals were painted by the Czech artist Ignatius Millim (1747–1820). The Altar of Our Lady dates to 1903.
Enlargement works were carried out in 1938, and restorations in 1973 and 2010.
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.
