In 1760, Contius moved to Riga in Courland, where he built an organ for the St. James's Cathedral, Riga.[5] He then worked in Tallinn in Estonia and became the leading organ builder there. In 1771, he returned to Riga and in 1773 was commissioned to build a new building in the great Holy Trinity Cathedral, Liepāja (Libau), which was completed in 1779.[5] In Valmiera, Contius opened a workshop together with Johann Andreas Stein (1752–1821) from Augsburg, who subsequently built further organs in Courland (1787 Cēsis, St. Johannis, 1788 Evele Wohlfahrtskirche).[6]
Works (selection)
Contius is known to have built several new organs, as well as repairs and a maintenance contract in the Duchy of Magdeburg, Courland and Estonia. Preserved are most of the Holy Trinity Cathedral, Liepāja, as well as the casing in the St. James's Cathedral in Riga. A replica of the organ in Liepāja has been under construction since 2016 in Leuven, Belgium.
New construction in facade and with parts of the organ by Johann Heinrich Joachim from about 1750, extended several times, lastly by Barnim Grüneberg in 1885 to become the largest organ in the world at that time, with IV/P, 131; preserved. → Organ of the Holy Trinity Cathedral, Liepāja[9] seit 2016 Replik in Sint Michiel in Leuven (Belgien).[10]
