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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
