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 Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
